A man and his wife were having some problems at home and were giving each other the silent treatment.
The next week, the man realized that he would need his wife to wake him at 5am for an early morning business flight to Chicago. Not wanting to be the first to break the silence (and lose), he wrote on a piece of paper, "Please wake me at 5am.
The next morning the man woke up, only to discover it was 9am 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 5am. Wake up."
