Charlie Brown's All-Stars

Charlie Brown's All-Stars, by Charles M Schulz is one of the cutest books I've read in a really long time (it is a book, not a cartoon).
It is the story of a bad team who gives their manager (Charlie Brown) a hard time and end up quitting. When the prospect of having real uniforms and real equipment fades, Charlie is more upset than the team but they don't realize how sad he is because of their own frustration towards him. After hearing the full story though, they band together and make him a uniform to show their loyalty and support.
With the moral at the end of loyalty towards friends, it becomes a didactic piece of literature. However, there are somethings in the book that can't possibly be understood by little children. For example, when Charlie is upset about the whole ordeal Linus (a character that walks around with a security blanket) notices that he's down. Charlie responds with, "You are a shrewd judge of human nature, Linus." This line is so ironic, because children typically aren't developed enough to judge human nature, nevermind comment on it,
This book might also be considered a tale about growing up. Linus, the boy that carries the security blanket, has to give it up to be used as fabric for the jersey for Charlie. He "suffered terribly as he saw his security blanket rapidly turned into a manager's uniform." However, the story finishes with Charlie and Linus together standing in the rain-Charlie wearing the blanket-turned-jersey while Linus is holding the corner of it with one hand and sucking on his thumb on the other. I loved the irony in this picture.
