One day, a little boy named Tim found a chain in his toy box. He was very happy. He believed the chain was magic. Tim wanted to show his friend, Lily, his magic chain. Tim went to Lily's house. He said, "Lily, look at my magic chain!" Lily looked at the chain and was frustrated. She did not believe it was magic. "It is not magic, Tim," she said. Tim was sad, but he still believed in his chain. Tim and Lily went to play outside. They saw a big tree. Tim took his magic chain and wrapped it around the tree. He said, "Watch, Lily!" Tim pulled the chain, and the tree shook. Lily was surprised. She now believed in Tim's magic chain too. They both laughed and played with the magic chain all day.
