Its a moral story and like all the moral stories, it takes a life time for people to understand what it means. Here is one story about a jackal and the grapes, that I remembered. I had heard it when I was a child. I started pondering upon it again, and did a little thinking and thought experiment into it. Here is how it went:
Old one : Jackal is trying to eat the grapes from a tree but he can't reach the branches so he tells his friends (hiding his disappointment), " You know, I could have reached there, but the grapes are really sour. "
But its not only one situation, I have found a new one:
New one: Jackal is trying to eat the grapes from a tree, he jumps for hours and finally reaches the branch and eats the grapes. But the grapes turns out to be sour. So he tells his friend (hiding his disappointment), "Oh my god, its the sweetest grapes I have ever tasted. Yummy .. "
Well what do you make out of these stories? I will end with this last one, chose your favorite:)
Last one: Jackal is trying to eat the grapes from a tree, he jumps for hours and finally reaches the branch and eats the grapes. But the grapes turns out to be sour. So he tells his friend, " What the hell!! Whats this? its too sour man. Let go try another tree."
There you go.
