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.
Agree on CrossFit. At my last job, there was a group of people who went together and would talk about it. For hours, every day. Got really sick of hearing about it. My wife even joined up for a while. While she had fun and it was good for her, I just didn’t have the patience to listen to her talk about it and all the gym gossip when she got home. I felt guilty knowing I should be more supportive, but I just couldn’t do it after hearing about WODs all day.
