For me it’s detailed describtions about people’s dreams.
Not only doesn’t your story make any sense, but you’re also telling me about something that didn’t even happen. It’s kind of like telling about an event, and then ending the story by saying you just made it all up, except with dreams you begin by telling it’s all made up. I’m already not interested before you even started.
I haven’t had people tell me to stfu, but I get eyes staring off into the distance and no engagement. So, yeah, I don’t talk certain subjects anymore.
