By the way, the subject of rest reminds me about this story I heard about a father who was playing cops and robbers with his 3 active sons in the back yard after dinner.
One of the boys "shot" his dad and yelled, "Bang! You’re dead!"
The dad fell dramatically to the ground. But then, he just lay there without moving. A watching neighbor ran over to see if he had been hurt in the fall.
When the neighbor bent over him, the overworked father opened one eye and said, "Shhh. Don’t give me away. This is the only chance I’ve had to rest all day."
