I took the eleven year old to the dentist. We arrived ten minutes early, no one was in the waiting room. They called him to the back about ten minutes after his appointment was supposed to start.
While we waited he griped, "What's taking so long? How many patients does he have?"
I said, "I don't know how many patients he has, but I know he has more patience than you!"
He groaned and started hitting me. But he had to laugh.
I sat and basked in his performance as the unwitting straight man.
