Query: The Giving Tree

Have you ever wanted to learn more about how to be a true friend? Well, have I got a book for you! I recently read the fiction book The Giving Tree by Shel Silverstein. The characters are a boy (who grows old) and a tree that might be in the boy's backyard. The boy and the tree have a friendship that lasts over a lifetime. The tree gives the boy all that he needs, and she is happy when he is happy. By reading this book, I learned how important it is to appreciate your friends. I recommend this book to people who already appreciate their friends, because they know that true friendships can last a lifetime.
