Amy is the tallest kid in her grade, and the fastest, and the best at math. She comes first during roll call and gets only straight As. Their school uses a Japanese kind of math called Kumon that lets you do however many problems you want in an hour. Amy likes to do a lot of problems without making mistakes. All the other kids disappear when she starts doing her Kumon. All she is aware of is those numbers. She loves numbers and letters and practices her handwriting every evening at home.
One day in the middle of long division a hand reaches inside her bubble and attaches itself to hers. Amy gasps without meaning to. She looks up and sees the principal.
Most children dread the appearance of the school principal at their desk, but Amy is so well behaved that it does not occur to her to worry. When the principal asks her to come outside with her please, Amy politely declines. But then when she sees the stunned scandalized eyes of the principal she puts her pencil down.
