I hope posting here helps a bit. People here are pretty accepting.
If anyone rejects you to amuse themselves that is extremely uncool.. to put it politely. I’m sorry I’m not much help but just wanted you to know I read your post.
I don’t personally enjoy most small talk much usually either.
Many people enjoy talking about music, films, books etc.
It’s probably safer to talk about neutral or positive topics if you don’t know the person, their triggers etc. Politics I avoid talking about.
Has a doctor or therapist given an opinion?
