One day, a small boy named Tim was playing in the park. He saw a smooth stone on the ground. He picked it up and thought it was very pretty. Tim wanted to show his friend, Sara, the stone. He knew she would like it too.
Tim found Sara by the big tree. "Look at my smooth stone," said Tim. "Wow, it is so nice!" said Sara. But when Tim tried to give it to Sara, the stone fell from his hand. It rolled away and went into a waste bin. Tim was sad, and Sara tried to help him reach for the stone.
A tall man saw them and helped Tim reach the stone. He took it out of the waste bin and gave it back to Tim. The man said, "You should be careful not to drop things into waste bins. You might lose them forever." Tim thanked the man and promised to be more careful.
Sara and Tim learned that they should always be careful with their things. They knew that if they were not careful, they could lose something important. And they also learned that it is good to ask for help when they need it.
