One day a rich boy bought a magic mirror. When he got home, he looked in the mirror. His face looked sad. He tried to smile and make funny faces, his face looked still sad. Then he did many happy things, but his face always looked sad.

“Oh, what a terrible mirror! It doesn’t work! ” he said angrily.

The next day on his way to buy some chocolate, he saw a little girl crying sadly. The rich boy went up to her and asked what had happened. The little girl said she couldn’t find her parents. “Don’t worry. I’ll help you,” the rich boy said. So they went to look for them together. Finally they found her parents. They were so thankful for his help. After the rich boy arrived home, he looked in the mirror as usual. To his surprise, his face looked very happy. The boy understood the magic of the mirror. The mirror could show the true feelings of its owner. This was true—the rich boy had helped that little girl so he felt really happy.
