Greed  

Once upon a time a stray dog was roaming about in search of food.He soon came to a butcher's shop there he found a bone with some meat on it.He picked it and ran
in search of a safe place.The dog came by a stream with a bridge over it.He decided to go across the stream.He started walking over the bridge slowly.Suddenly he chanced to see his reflection in the water.He could not understand that he was looking at his own shadow.He thought it was another dog with a meaty bone in his mouth.
The greedy dog decided to snatch the bone from the other dog.He flew at his
own shadow in the water.As he jumped into the water,he let go of his own bone.
The greedy dog had now nothing to eat.
