What I struggle with is that I don't use IG and other social media. And a lot of people's polite/casual conversations are entirely based on that stuff.
I notice I have an easy time talking to people over 50, but under 40... it's like I live on a different planet. We have nothing in common to really talk about because they just reference social media stuff and I have no context for it. I quit a bunch of stuff recently because all the new people coming in started straight up being rude/insulting me because my life isn't governed by chasing social media trends or agonizing about response times like theirs is. I get told off by a lot of new people because I don't text back fast enough and they take it as a personal attack or something when I said 'well if it's that important why not call and have real time voice conversation'.
I also prefer face to face interaction and not constantly being in discord/slack chats, which apparently is how everyone under 30 socializes these days.
