Most of the social gatherings I’ve been to have been set up with coworkers. Maybe I was conditioned by the American education system but I don’t think I’ve ever made a friend outside of a place that we both were expected to go to consistently. I’m not very familiar with constructs outside of that if I’m honest.
Don’t get me wrong I have certainly had my fair share of bad work interactions but most were benign and some became friends. Although I’m not advocating for the office, I just think people like me wouldn’t do very well without other changes, and I think there are more people who don’t know how to make adult friends than we think. I’m not even an introvert, I just don’t go to any place often enough to make friends from it
