A dog stole apiece of meat from the butcher at market. It ran rapidly to the middle of the bridge. While it was looking down the water under the bridge, it saw another dog with a piece of meat in its mouth. That piece of meat was bigger and the dog would like to take it.
While the dog was growling, the meat in its mouth was dropped down into the water. Suddenly the other dog disappeared. The dog was very surprised and finally it was angry with its own greediness.
Another dog was only its shadow i the water.
If it had not been greedy, it would not have lost the meat.
