Hats!
(Book)

When three friends meet a mean boy who insults their hats, they make a friend of him. When a young boy enters a hat shop and sees there is a sale that day, he carefully chooses the perfect hat. Proudly wearing his new hat, he walks through town. When he reaches the park, a bully tells him, "Dumb hat!" The boy is crushed-is his hat really dumb? But other kids who come along think the hat is pretty cool, and in a surprise twist, the boy and his new friends turn the tables on the bully.
