One day, a little ball was rolling down a hill. It was having so much fun. The ball had a great idea to roll faster and faster. As it rolled, it saw a big tree and thought it would be fun to roll around it.
The ball started to roll around the big tree, but it got frustrated. It was not easy to roll around the tree because of the roots. The ball tried again and again, but it just couldn't do it. The ball was very sad and wanted to go back to the hill.
Suddenly, the ball saw a big dog coming. The dog wanted to play with the ball. The ball thought the dog would help it roll around the tree. But the dog picked up the ball and ran away. The ball was not happy and never saw the hill or the tree again.
