Once upon a time, there was a big blackboard in a small room. One day, a boy named Tom came into the room. Tom saw the blackboard and wanted to draw on it. He picked up a piece of chalk and started to draw a big sun.
Suddenly, Tom's friend, Sally, came into the room. She saw Tom drawing on the blackboard and said, "Tom, you should not draw on that blackboard. It is not yours." Tom felt guilty and stopped drawing. He looked at Sally and said, "I am sorry, I did not know."
Just then, they heard a noise coming from the corner of the room. They went to see what it was. They found a big, old apple that was starting to rot. Tom and Sally looked at each other, surprised. They did not expect to find a rotting apple in the room.
Sally had an idea. She picked up the apple and said, "Let's go outside and throw this away. Then we can play together." Tom agreed, and they left the room, forgetting all about the blackboard.
From that day on, Tom and Sally always played together and never felt guilty again. They learned that it is important to share and take care of things, even if they are not yours.
