Real or Imagined?

Mrs. Bower's second grade class at Schurz School in Watertown, Wisconsin wrote a big letter with a couple of questions.

Q: How many books have you written so far?
A: I've illustrated 242 books, and I've written the stories for 121 of those books. Do you have all of my books?

Q: We just read OLIVER BUTTON IS A SISSY. We were wondering if you wrote this story about something that happened to you when you were young?
A: The story is loosely based on incidents from my life.
