Plot Summary: Tucker loves ballet-even though some people don't understand his passion for dancing.

This book is trying to say that anyone can do anything, but mostly ends up saying that boys can’t dance ballet unless it's useful to manly things like football. But it's true that boys that do dance are teased for it and this book definitely makes you empathize with Tucker, who just wants to do what he likes.
