There was once a donkey who was tired of being a donkey. "l wish l were a lion or tiger," he thought. So one day when he found a lion s skin he put it on. Then he began trying to frighten whoever he happened to meet along the road. Everyone he met believed he was lion, and ran away as quickly as they could on seeing him approach. Delighted by the success of his trick, the donkey brayed loudly. The fox guessed who was hiding under the lion s skin and, laughing, he said, "My dear fried , you can come out now. l have been afraid of you too, if l hadn t heard your loud voice."
