Because I don’t, and pretending to feels dishonest. I’ll listen if they want to talk about it, but I’m not going to act interested, and I certainly won’t ask about it on my own. What I’m trying to figure out is whether people actually care, or if they’re just playing a social game that I’m simply not interested in.
I’m probably on the autistic spectrum, which likely explains this to some extent. But that’s not an excuse - being an asshole is perfectly compatible with autism, so before dunking on me, please realise I probably agree with your criticism.
About a new baby? Yes, show me pictures. Also your new kittens, kitchen, a cake you made, a painting you painted, sure, yes.

But these weaker social connections are so important to life and to society. You can’t sort people into friends or strangers, care and don’t care. There is a lot of room in between - people you know but aren’t close with are most of the people you know. It doesn’t matter if you are just following the forms, that’s fine. Keep on doing that, be nice.
