A duck was once swimming along the river looking for fish. The whole day passed without her finding a single one. When night came she saw the moon reflected on the water, and thinking it was a fish she dived down to catch it. The other ducks saw her, and they all made fun of her. From that day the duck was so ashamed and so timid, that even when she did see a fish under water she would not try to catch it, and before long she died of hunger. By Leo Tolstoy
