As I've gotten older I struggle to make new friendships, but I still keep up most of my older friendships. The friendships that I've dropped or let fade away are mostly because they were toxic relationships in some regard or alternatively that I'm simply in a much different place in my life than the other person. I still have multiple friends that I've known for more than 20 years, but nobody left from high school or earlier that I keep in touch with. My path just diverged so much from others once I left my hometown, and while one of my long-term friendships is with someone from the same home town, we both live in the same city now over a thousand miles away.

It's harder to make the time for new relationships when you're older, and you frankly just have less patience for people who should know better and nearly infinite patience for those who couldn't have known better. Ironically, I'm at a point in my life where what I'd like to do the most is teach younger people useful skills that I've learned, but that's a difficult thing to do as most younger people have no interest in interacting with people significantly older than them, and the social context has changed so much now compared to the past that it's socially frowned upon unless you are directly familial related. I've guest lectured at a local college a few times, and I've actually considered doing full-time teaching after I retire from tech, but the types of things I want to teach aren't really a focus in school (think stuff you'd learn in shop, home-ec, or stuff that was never taught).

I have a young niece I teach things and there's neighborhood kids that come around when I'm doing project car stuff in the driveway, but generally it's fairly disappointing to me how most adults stop wanting to learn by the time they're just 20-25, and people are fully stuck in to their ways by 30. I'm still learning new things every day, and I have never lost my desire to learn or to self-improve. I am a different person than I was 5 years ago or 10 years ago, and I think better than I was. There's no reason I should ever stop getting better and learn new things, but just knowing things doesn't make anything better, it helps to also teach others or use your knowledge to help people. So many folks are just completely resistant to the idea of learning something or accepting help.
