A man and his wife had been arguing all night, and as bedtime approached neither was speaking to the other. It was not unusual for the pair to continue this war of silence for two or three days. However, on this occasion the man was concerned; he needed to be awake at 4:30am the next morning to catch an important flight and being a very heavy sleeper, he normally relied on his wife to wake him.
Cleverly (so he thought), while his wife was in the bathroom, he wrote on a piece of paper: “Please wake me at 4:30am – I have an important flight to catch.”
He put the note on his wife’s pillow, then turned over and went to sleep.
