what do you like talking about? try talking about it, even if people hate it.

do the things you enjoy, as long as it isn't murder or whatever. talk about the things you enjoy. do the things you enjoy with other people. conversations will emerge naturally

sure, you should give other people space to talk about their stuff, but you shouldn't feel obligated to enjoy it. it's just a nicety for if they're in the same situation as you. most of all, the fact that conversations are boring doesn't mean you're broken. you should be allowed to be bored (and allowed to be kind of angry about it!)

not everyone should be expected to be perfect neurotypical conversationalists. Oh, god forbid, not everyone even needs to talk all the time!
