It's always so funny that this is brought up on HN as a reason for lack of socialization or problem so often. One of the biggest and most durable parts of my social life is being a member of a political party, which I have been in since I was 16 years old.
Being involved in civic/political life means you have connections with people from all walks of life across all generations and backgrounds. just wanting to chill is the actual problem because I don't think these suburban soccermom type social circles sustain meaningful relationships. Participating in public life is the most straightforward way to build social relationships that matter.
There was another great post here a few weeks ago from someone explaining why he continues to serve in the British Yeomanry. https://chrisseaton.com/army/
