Once upon a time, there was a little boy named Tim. Tim had a big yellow ball that he loved to play with. Every day, he would take the ball to the park to play.
One day, while Tim was playing with his yellow ball, it rolled away and got stuck in a tree. Tim was sad and wanted to get his ball back. So, he decided to climb the tree. As he climbed higher and higher, he saw a little bird sitting on a branch.
The little bird was very obedient and wanted to help Tim. The bird flew up and grabbed the yellow ball with its beak. Just as Tim thought he would get his ball back, the bird flew away with it! Tim was very surprised and didn't know what to do. He climbed down the tree and went home.
The next day, Tim went back to the park and saw the little bird again. This time, the bird brought the yellow ball back and dropped it at Tim's feet. The bird had been playing a game with Tim! They both laughed and played together all day long. From that day on, Tim and the little bird became best friends.
