Once upon a time, in a small house, there was a little dog. The dog had a toy ball. He loved to play with his ball all day. One day, he wanted to play outside. He was very happy.
The dog took his ball and went outside. He saw a big hill. The dog wanted to play on the hill. He ran up the hill and dropped his ball. The ball rolled down the hill very fast. The dog was worried.
He ran after the ball, but it was too fast. The ball went to the bottom of the hill and hit a big rock. The ball broke into pieces. The dog was very sad. He went back home with a hurt heel and no ball to play with.
