One day a crow found a piece of meat. She picked it up in her mouth and flew to a tall tree. She was just going to eat the meat when a fox saw her. He came and stood under the tree and said," How pretty you are! My dear friend, you must be the most beautiful bird in the world."
The crow was very happy by these words. Then the fox said," I can you see your pretty face, but I have not heard your voice. Why don't you sing a song?"
The crow opened her mouth and began to sing. As she opened her mouth, she lost her meat. The fox picked up the meat at once and went away with it. The crow was very angy.
