Once upon a time there was a dog lived in a village with his master. One day the dog had a large juicy bone and decided to enjoy eating that in a lonely place. So ran away from the place and started towards a lonely place. On his way he had to cross a bridge over a small river.
While it was crossing the bridge it saw his reflection in the water from the bridge. He could not follow that it was his shadow. He thought it to be another dog with a bone in his mouth.
Being greedy by nature he wanted that bone too. So as his nature it barked at the other dog. His bone fell into the water and vanished in a second. The dog has lost the bone for his greediness.
Moral: Greedy may loose everything in your life.
