Big wakes up one morning and thinks: something is missing from my house. While he is looking for this something there's a knock at the door. And in walks Small. Big's first ever visitor; looking to have fun. Big, excited to have a guest, shows Small the garden swing that's hanging from the apple tree. But zooming through the air on a big swing isn't a lot of fun for a Small, especially when he ends up with a smooshed nose . What is fun, however, is a small model car that Big brings out of his tool shed. Fun, you see, comes in different sizes. And watching Small race around the room makes Big realize that's what is missing from the house. A Small - and a friend. A best friend. And Small, too, has found his best friend and a home. When Small knocks on Big's front door, Big's life will never be the same again!
