A man and his wife were having some problems and giving each other the silent treatment. The man realized that he'd need his wife to wake him the next morning at 5:00 AM for an early flight to Chicago. Not wanting to be the first to break the silence, he wrote on a piece of paper, "Please wake me at 5:00 a.m." The next morning the man woke up, only to discover it was 9:00 a.m. and that he had missed his flight. Furious, he was about to go and see why his wife hadn't woken him when he noticed a piece of paper by the bed. The paper said, "It is 5:00 a.m. Wake up."
