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.
Gossip. Even talking about gossip.
Can’t stand when someone recites a previous conversation instead of telling me the subject and results of the conversation. He said blah blah blah blah, she said blah blah blah blah, then she said blah blah blah… 🤦
