How Socializing Can Get Easier And Harder As You Grow Older
People who struggle socially are often on the younger side. They can worry the window to have a good social life is closing on them, if they haven't missed it already. They've probably heard that high school and college are the easiest places to make friends, and it gets way harder after that. They can generally have a bleak outlook on what the social world has in store for them as they get older.
In fact, in many ways the social world is easier to navigate as you get into your mid-twenties and beyond. Though in others ways it's tougher than during your school years. I'll cover both in this article. I do think the positives outweigh the negatives, so I'll go over them first:
Ways socializing gets easier with age
You just have more time to practice and catch up to everyone
This is the biggest factor of all. Some people come out of high school or university unsatisfied with how their social lives have gone so far. They look back and are bummed out that they didn't have many friends, or haven't had a relationship yet, or didn't get to take part in all the usual college experiences, like going to parties. High school and college are important, but when you're done with them you're still quite young. Many people start to get the hang of socializing in the years after graduating, just because they have more time to practice and figure things out on their own.
A lot of people seem to go through a natural trajectory where they're really awkward and shy in high school, a lot better, but still struggling somewhat in college, and then by their mid-twenties they've gotten past the worst of it. There was nothing intrinsically wrong with them when they were younger. They just needed a little more time to pick up some social concepts, learn to work around their naturally inhibited personality, and to catch up with everyone after getting a late start. Others don't hit their stride until their mid-thirties or older, but once they're caught up they can have as rewarding a social life as anyone else.
You've have had time to take on new interests and round yourself out more
When you're younger you just haven't had as much time to develop a range of interests. I think people more easily fit into stereotypes when they're in high school simply because of they haven't had a chance to move beyond the handful of things they naturally got interested in first. As people get older they've had the time to pick up additional hobbies and flesh out their personality. They can even accidentally get into pastimes they never would have guessed they'd enjoy one day. Of course, the more interests you've dabbled in over the years, the easier a time you'll have relating to people and making conversation with them. You'll also be able to do more things with your friends (e.g., you can join them when they go mountain biking, instead of bowing out and saying you'll only meet them for dinner later).
People tend to get more comfortable with themselves as they get older
Many people have personalities, interests, or appearances that go against what society says are the "right" ones to have. When they're younger they can feel really conflicted about this. Following their natural dispositions seems to make them the happiest, but they may also take society's messages to heart and tell themselves things like, "I'm such a loser for being into anime. Why can't I just like cars and golf and whatever and be a 'normal' person?"
As people age they tend to make peace with the ways they're different. They learn to be more sure of themselves and not be too swayed by what everyone else thinks. They decide there's nothing wrong with being how they are, and some will like it and others won't, and that they can handle that. Some people aren't even that old before they develop that mentality. Practically, this means they act and feel more quietly confident, and they no longer hesitate to seek out the type of social life that works best for them (e.g., only having a few friends, skipping on rowdy parties, being unembarrassed about joining a tabletop gaming club).
This isn't to say that once someone becomes comfortable with themselves they rigidly lock their personality down for all time. You can still be open to changing or developing new facets of yourself. You can still identify traits that you want to improve upon. But you don't beat yourself up just because you want to spend a Saturday afternoon reading a fantasy novel.
You can hang out with a wider range of people
In high school and college you're more restricted in who you can spend time with. I don't even mean 80's teen movie stuff like how a Prep can't hang out with a Goth. When you're younger there's an unwritten expectation that you're going to be friends with people close to your own age. But if someone is twenty eight there's nothing stopping them from hanging out with their 45-year-old co-worker, or the 37-year-old they play poker with. It's okay to have a wider range of friends, and once you're out in the world you get exposed to a broader group of people.
Sometimes people will tell you that they don't have a ton of friends because they feel like they just don't have much in common with their similar-age peers. When you get older this doesn't hold you back as much. If you feel like you want to hang around more experienced, mature types, or people from a very specific niche or subculture that's suited to you, then you can seek them out.
You usually have more resources to find the right kind of social environment for you
Anyone will seem more awkward and out of place if they're plopped in an environment that's not a good fit for them and doesn't value what they're about. When you're younger you're stuck wherever your parents chose to live. If someone goes to university, they don't always have a ton of options about what school to go to either.
When people get older and gain more independence and money they get more say about what kind of environment they want to be in. Some people come across as "late bloomers" not because they totally changed, but because they were finally able to put themselves in a setting where their true selves could blossom. They can get out of their small, boring town and move to a new city that's filled with their type of people. They can choose a job that plays to their strengths and style of socializing. They may live in an area that's not for them, but buy a car and easily be able to drive somewhere better on the weekends. If they prefer living alone they can afford to get their own place.
People aren't jerks as much
Everyone knows that kids and teenagers can be really nasty to each other. I don't want to oversimplify things and say adults are never mean-spirited or abusive. They are. They can also be jerks to each other in much more subtle, insidious ways. But in general adults are nicer and more tolerant in the face of social awkwardness. If a young girl is acting a bit shy her classmates could very well make fun of her to her face. An adult is more likely to be polite, patient, understanding, and accommodating. They may try to subtly include or help someone who's being quiet at a party. Especially in certain workplace environments, people are a lot more behaved. Even if an adult is put off by someone who's socially awkward, they're more likely to just bite their tongue and go on with their day, rather than try to make the person's life miserable.
In a lot of ways, this all creates an atmosphere where it's easier and safer for someone who struggles with social skills to be themselves, and to work through their issues. Yeah, not everything will be perfect. For example, if someone tries to invite an acquaintance out who's not interested, they may still get a "polite" run around. But at least they can be pretty sure they won't be openly mocked for asking the wrong person to see a concert with them.
Other people don't care what you do as much
This is a bit related to the idea of people not being jerks. When you're in high school a diverse group of people are all forced to be in close proximity to each other for most of the week. Even when you try to tell yourself you shouldn't care what everyone else is doing, you can't help but know anyway, and get sucked into it to a degree. This is way less of a problem in college, and almost totally goes away after that. When you're older you have way more freedom to do your own thing and not get a hard time for it. For one, people can't practically keep track of what you do. It's not like they have to see you in class. They're also busy with their own lives and have better things to do than worry about how someone else spends their days.
You've had more time to build other successes, positive habits, and skills, which you can carry over to the social world
For example, if you've done well in your career that can give you a sense of self-worth that you can bring to your social interactions ("Who cares what she thinks of me? Even if she doesn't like me it doesn't change the fact that I've accomplished X,Y,Z." As a teenager or college student you may not have these achievements to draw on. I'm not saying career success can always automatically fix your self-esteem, or that you can't feel confident if you don't have a good resume. I just mean that sometimes knowing we've done well in one domain can make you feel more self-assured.
As you've gotten older you've likely built up useful skills and habits that can also help you socially. They could be broadly useful ones like self-discipline, tolerance for discomfort and uncertainty, or being able to think long-term. It's easy to see how those would help you get out there to put in some social practice, and not give up too easily. Your skills could also be more practical ones which open up social opportunities (e.g., knowing how to cook, so you can throw dinner parties for your friends; knowing how to drive so you can go to events in neighboring towns).
Ways socializing can get harder as you get older
I know I painted a pretty positive picture above, and I think those factors are more powerful than the ones below. Most of the points in this section share a common theme of it being harder to meet people. None of this is to say that it's impossible to make friends when you're older, but I'd say it is a little trickier. The things I mention below are fairly common complaints people make.
You just have to work harder to meet people
Like I said, everyone's heard it's way easier to meet people in high school and college. You spend a good chunk of your day surrounded by hundreds, or thousands, of your peers. You may even live in a building full of them. Once you're out of school you often have to hustle more to make friends. Though like I just said, "harder" doesn't mean "impossible". These articles go into detail about what you can do:
Other people are busier
I think it starts to happen at a different age for everyone, but there will be a point when you notice that the people in your life just don't have as much free time to hang out anymore. They're too busy with their jobs, partners, and families. If you're trying to make new friends, or keep a friendship going, this can really get in the way. It's not enough to meet someone you get along with. They also have to have enough breaks in their schedule to hang out with you. Not that easy when they have to work on the house, drive their kids to soccer tournaments, and visit their in-laws every weekend. Not to mention, you may be just as busy with the same kinds of things yourself. Though again, "busier" doesn't mean "never, ever available". And with time people's schedules can clear up. Like they may start wanting to hang out more as their kids get older and more independent.
People may already have existing, long-time social groups
Besides having to compete with people's hectic schedules, some of the potential friends you meet when you're a bit older already have well-established social circles, which gives them little motivation to add a new buddy to their routine. You may meet someone you get along with at work, but when they do get time off from their family, they spend the weekend with a bunch of friends they've known since high school. It can be really tough to break into a group who have twenty years of shared experiences between them. Once more, you don't want to be too defeatist about this kind of thing. Not every last person has a dozen buddies they met in Kindergarten.
People can be physically harder to access
In high school and college everyone is obviously at the same school. Many of the people you meet also live fairly close by, maybe even in the same dorm two floors down. In university it's not hard at all to gather up ten people on a Friday night. When you're older your friends can be all over the place. One could live in the suburbs half an hour north of the city. Another could live in a feeder community an hour to the west of it. These little things make it that much harder to organize get togethers, or to hang out spontaneously.
People can be a little too polite and indifferent to you
I already hinted at this in the previous section, where I talked about how people are less likely to be jerks, or to care what you do. Sometimes this tactfulness goes a bit too far and can leave older people who still struggle socially really lost and frustrated. A middle-aged person may not have as many social problems as they did in college, but still have things they want to work on. However, they can't seem to get anywhere with anyone. They know they're not having the success they want. They assume they must be doing something wrong, but no one will give them any clue about what it may be.
Everyone just seems to quietly exclude them. They try to invite people out, but are met with walls of friendly, reasonable excuses. Co-workers socialize at the office, but they're on the outside looking in. Everyone has their own stuff going on and aren't going to take it upon themselves to try to help them out. Even if they want some direct feedback, everyone is too nice to offer it. At least in high school someone might get annoyed and tell them, "Ugh, you're so desperate and needy! And you wear the same cloths every day!" That's mean, but at least it's something to go on.
