Once a fox was famished with hunger. He was thirsty too. He then moved hither and thither in search of food. At last, he entered a vineyard. The sun-ripened grapes were hanging from the vines high up. It was too high for him to reach. Aiming at the lowest bunch he took a run and a jump. But he missed. He tried again and again but in vain. At last, he ran out of energy, became exhausted and tired. He then last came out of the vineyard, muttering.”I never really wanted these grapes. I am sure they must be sour.”
Moral: Fools despise what they cannot achieve.
