Once upon a time, there was a boy named Tim. Tim had cool sunglasses. He loved to run fast in the sun. One day, Tim put on his sunglasses and went outside to play. He felt happy.
As he ran fast, Tim saw a big dog. The dog had Tim's sunglasses on its head! Tim felt surprised. The dog ran fast too, and Tim chased the dog to get his sunglasses back. They ran and ran, and Tim felt excited.
At last, the dog stopped and looked at Tim. The dog took off the sunglasses and gave them back to Tim. It turns out the dog just wanted to play! Tim felt happy again. From that day on, Tim and the dog became best friends and played together every day.
