This, I want to talk about something, not rehash the same comments about the weather. I don't even mind when people talk about their vacations or their kids, but I want to know interesting specific details, not nonsense generalities just for the sake of talking. I love talking to people about their careers, but I want to learn the weird minutiae that isn't common knowledge.
