Once upon a time, there was a tall tree in a big park. A little bird lived in the tree. The bird loved to soar high in the sky. It would fly up and down, and all around the park. The bird was very happy.
One day, the bird saw a dog on a leash. The dog was with a boy. The boy and the dog were playing catch with a ball. The bird wanted to play too, so it flew down to join them. They all played together and had lots of fun.
But then, something unexpected happened. The leash came off the dog. The dog started to run very fast. The bird tried to help the boy catch the dog. The bird flew high and saw the dog. The bird was able to grab the leash with its beak and bring it back to the boy. The boy was so happy and thanked the bird. From that day on, they all became best friends and played together every day.
