Once upon a time, there was a little girl named Amy. She had a big bag of marbles. Amy loved her marbles because they were pretty and fun to play with. She had a friend named Tim. Tim and Amy liked to play together. They felt comfortable when they were with each other.
One day, Amy and Tim were playing with the marbles in the park. Amy said, "Tim, be careful with the marbles, or they will get lost." Tim nodded and said, "Okay, I will be careful." But Tim was not careful. He threw a marble too hard, and it went far away. They both looked for the marble, but they could not find it. Amy was sad.
Later, as they were leaving the park, Amy saw a big dog. It had something shiny in its mouth. Amy screamed, "Tim, look! The dog has my marble!" But the dog ran away with the marble, and they could not catch it. Amy and Tim were very sad. They went home without the marble, and they knew they should have been more careful.
