By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done. Genesis 2:2-3 (NIV)
Life Lesson #2 from Baxter, the Cavapoo: Some days you just gotta nap.
P.S. Even the folks in The Calling of Ella McFarland took naps once in awhile.
