<I><b>You have to write!</b></i> It's a class assignment. But you have nothing to write about. All the other kids seem to have something to tell because they start in right away. What can you do? Stop and think. No one else can tell <I>your</i> stories -- about your family, your dog or cat. No one else can tell how it was when your library book got soaked in the rain. <P> But what if you don't like what you write? There are all sorts of ways to change it, to make it better. Keep on playing with your words, putting them together in different ways. You want whatever you write to be good. It will get better and better as you work on it. <P> This is an encouraging book, sympathetically illustrated by Teresa Flavin's charming pictures, for all young readers who worry when they're told to write something.
