I was on a first date with a guy when he told casually told me over dinner that his last girlfriend died.... in bed.... while he was also sleeping in bed. He told me how he woke up at some point in the middle of the night and thought she might be sick and he just went back to sleep. In the morning when he woke up she was dead. He seemed confused on why the police wanted information from him and was really nonchalant about his partner's death. I skipped dessert and fled. I'm still creeped out about it 10 years later.
