It happened that a Dog had got a piece of meat and was carrying it home in his mouth to eat it in peace.
Now on his way home he had to cross a plank lying across a running brook. As he crossed, he looked down and saw his own shadow reflected in the water beneath. Thinking it was another dog with another piece of meat, he made up his mind to have that also. So he made a snap at the shadow in the water, but as he opened his mouth the piece of meat he was carrying fell out, dropped into the water, and was gone.
Moral of the story: It is not wise to be too greedy.
Wanting more than our share often leads to loosing what we already have. Be satisfied and thankful for what you have, rather than being greedy trying to accumulate more than you require.
