One spring day some naughty boys were playing near a pond. They began to throw stones into the water. In the pond lived many frogs were much afraid of the boys, for the stones hurt some of the frogs. At last an old frog lifted his head out of the water and said, “Boys, please don’t throw stones at us.” The boys said, “We are only playing.” “I know that, but please stop throwing stones, my boys. What is play to you is death to us,” said the old frog. So the boys stopped throwing stones and went away.
