Milestone: First Lost Tooth

7 year old ES just lost his first tooth. He was the only kid in his first grade class last year NOT to lose a tooth.

When he came home from school (they start the school year in early August in Hawaii), my wife asked him if he told his teacher he lost a tooth.

"No," he said.

"Why not?" she asked.

"Because I was afraid she would give me more homework."

Huh???

He frequently impresses me with how smart he is. He's like a sponge absorbing all sorts of facts about things. Sometimes he throws me for a loop with his logic on things. Why would losing a tooth cause your teacher to give you more homework?
