Once A Doog found a bone in the forest. He held the bone in his mouse. As he is crossing a stream. He looked into the water. And saw another dog holding a bone in his mouse. He wanted the other bone also. So, He barks to the dog. He opens his mouse to bark. The bone fills into the water. He lost the bone. It was not another dog in the water. It was his own reflection. The greedy dog had learned a lesson.
