One afternoon a fox was walking through the forest and spotted a bunch of grapes hanging from over a lofty branch.
“Just the thing to quench my thirst,” he thought.
Taking a few steps back, the fox jumped and just missed the hanging grapes.
Again the fox took a few paces back and tried to reach them but still failed.
Finally, giving up, the fox turned up his nose and said;
“They're probably sour anyway,” and proceeded to walk away.
Moral of the story:
It's easy to despise what you can't have.
