I think the problem for me is that going and doing things like that regularly requires a lot of time, which would mean I would have to sacrifice my own projects or sacrifice time with my kid, both of which I don’t want to do. I don’t really want to make friends with coworkers, because I tend to consider them a liability. Relationships can change, and as you get to know someone you can find out things about them that stops you from wanting to be friends (they’re a secret republican, etc). If a work friendship goes south, you now have a potentially hostile coworker with intimate knowledge about your life, which can directly impact your livelihood. Sooo I have like three friends, each of whom are from my twenties or earlier, and two of whom live hundreds of miles away. I’m not unhappy, though.
