Does anyone else feel a disconnect in culture in which it feels difficult to meet others?
Yes, my wife and I feel that, and find it difficult to meet others and develop a social life. We are both introverts and rather withheld and have modest social needs to begin with, which doesn't help.
Neither of us had significant difficulty dating people when we were single, but that's in my view actually an easier scenario for someone who is not socially anxious or unconfident. The bigger problem is in developing "meaningful" / "committed" friendships. People have arbitrary notions who to include / exclude from such considerations. For example there's a nice couple next door to us but he's fixated on people within a few years of his age; he's 71 and I'm 61 so I'm just not "his age". In addition, I don't play his favored sports. I think those are dumb considerations at our age. On the other side of us is a couple who are somewhat the social climber types and they gauge us as Not That Useful to improving their social status because we don't play those kinds of games. And so forth.
Definitely. I don't know what people are talking about when they discuss TV, pop/country music, or the movies at the theater. They don't know what I'm talking about in books or obscure music.
It's lonely. I find I have a lot more in common with people I meet online.
