The Farmer and the Snake
Once upon a time a farmer was walking through his field on cold winter morning. Suddenly he noticed that a snake was lying almost dead with cold. The farmer knew that it was deadly. But he took pity on it and brought it home. He kept it under a blanket and soon it revived. After sometime the snake was about to bite the farmer’s son. The farmer realized his mistake and chased the snake away from his home.
Moral: Don’t expect gratitude from the wicked.
