Once upon a time a fox was very hungry. He was searching for food. He reached a garden. He saw a beautiful bunch of ripe grapes hanging from a vine trained along the branches of a tree. The grapes seemed ready to burst with juice, and the Fox’s mouth watered as he gazed longingly at them.
The bunch of grapes hung from a high branch. The fox had to jump for it. He tried again and again to reach those grapes but still failed. After several failed attempts, the fox gave up and walked away saying that the grapes are sour.
Moral: You often hate what you can’t have.
