We were sitting in a fine restaurant when my wife looks over at a nearby table and sees a man in a drunken stupor. I said "I notice you've been watching that man for some time now. Do you know him?" "Yes" she replies, "He's my ex-husband, and has been drinking like that since I left him seven years ago." I said, "That's remarkable, I wouldn't think anybody could celebrate that long." She hasn't spoken to me since - did I say something wrong?
