Once upon a time, there was a big red ball. The ball had a little spot on it. One day, the ball met a small blue ball. The blue ball said, "Hello! Can we play together?" The red ball said, "No! I am too big and you are too small. Go away!"
The blue ball felt sad and went away. It met a little green ball. The green ball was very nice. They played together and had fun. The red ball saw them and felt a pinch in its heart. It wanted to play too, but it was too selfish to share with others.
In the end, the red ball stayed alone with its spot. The blue and green balls played together and had lots of fun. The red ball wished it could join, but it was too late. It had learned that being selfish only brings a bad ending.
