The Dog and His Shadow
One day he walked in while biting a piece of fresh meat. While walking along the river, he saw another dog which was also biting a piece of meat without him knowing that it was his own reflection.
The dog wanted the meat too and tried to snatch it. As a result, the meat he bit into fell into the river and he failed to enjoy it.
The moral message from this example of a fable story is don't be greedy and want to usurp other people's rights, because each person has their own sustenance
