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