Early one morning, a mother went in to wake up her son.
"Wake up, son. It's time to go to school!"
Son: "But why, Mom? I don't want to go."
Mother: "Give me two reasons why you don't want to go."
Son: "Well, the kids hate me, and the teachers too hate me"
Mother: "Oh, that's no reason not to go to school. Come on now and get ready."
Son: "Give me two reasons why I should go to school."
Mother: "Well, for one, you're 52 years old. And for another, you're the Principal!"
