翻译英文小故事：The Fox and the Grapes

Once upon a time, a hungry fox saw a bunch of juicy grapes hanging from a vine. The fox tried jumping to reach the grapes, but they were too high. After many failed attempts, the fox finally gave up and walked away, saying to himself: "Those grapes are probably sour anyway."

Moral of the story: It is easy to despise what you cannot have.
