A man came home from work late, tired and irritated, to find his five-year old son waiting for him at the door. "Daddy, may I ask you a question" "Yes, what is it" answered the man. "Daddy, how much do you make an hour" "If you must know, I make twenty dollars an hour." "Oh," the little boy replied, with his head down. Looking up, he said, "Daddy, may I please borrow ten dollars from you" The father gets very angry, because he thought his son wanted to buy toys with the money, but he still gave the money to his son. Then the little boy said, “Daddy, I have twenty dollars now. Can I buy an hour of your time Please come home early tomorrow. I would like to have dinner with you.\ The father made ______ an hour.
