Once there was a dog. Every day the butcher gave him a bone to enjoy. The dog sat near the shop to enjoy the bone.
Then, one day, the dog thought that he should take the bone somewhere safer and eat it there. So he took the bone and decided to look for a safer place.
While looking for a place, he came upon a bridge. While on the bridge, he saw another dog in the water.
The other dog had a bone that was twice the size of the dog's bone. The dog thought, “I must get the bigger bone.” Thinking that he started barking at the other dog and jumped into the water to attack the other dog.
In the process, the dog lost his own bone. He did not even get the other bone as it was just a shadow.
Moral: Greed can often make you lose what you have in hand.
