As I was teaching my last block today, I looked over at a couple of my students and noticed that the back of one of their necks had a smiley face drawn on it. I saw a brown marker in the hand of the boy sitting behind him and came to the correct conclusion that he had drawn the face on the kid's neck.
I asked the boy with the marker when he had drawn the face. He looked at the clock and cotemplated for a few moments and said, "Oh, about...five minutes ago."
Later that hour I looked again and the face had become a whole person!
I was able to take a picture of the little person on the kid's neck before the bell rang.
