The Fox and the Grapes

Once upon a time, there was a fox who was feeling very hungry. While walking in the forest, he spotted a beautiful bunch of grapes hanging from a vine. The fox began to salivate, and he wanted to eat the grapes badly.

But when he attempted to reach them, he realized that they were too high up for him to reach with his short legs. Even after jumping several times, he couldn't get to the grapes. The fox tries again and again, but each time he failed to reach the grapes.

Feeling disappointed, the fox tried to console himself by saying, "Those grapes are probably sour and not very tasty anyway." This is what we call "sour grapes" - when someone disparages something that they've failed to obtain or achieve.

So, the lesson here is to never give up on something just because it seems difficult or unattainable. Instead of giving up, try harder and don't make excuses. It's always better to believe in yourself and put in the effort to achieve your goals, rather than belittle the things you can’t have or obtain.
