Even my kids’ friends’ parents are often tedious to hang out with. “Can you believe <insert thing from popular TV>?” Or some town gossip that is interesting only to the other half of the conversation.
I have non-work friends, most of which I met locally, but there’s a common interest beyond “you happen to get your mail delivered by the same person”.
Work socializing has some advantages for introverts. You don’t generally have a lack of topics to discuss; if one gets boring, you can switch to another.
