Once upon a time a hungry fox was roaming in search of food. He was feeling weak and tired due to hunger. Luckily he came to a garden. There he saw a grape-vine laden with bunches of grapes. They looked quite ripe and juicy.
The fox looked at the grapes with longing eyes and licked his chops. He was sure that he would eat them up and appease his hunger. But he was feeling weak.
So, the fox sat down for a while to take rest. Then feeling refreshed he jumped as high as he could to get at the grapes. But alas ! the bunches were too high for him.
The fox once again rested for a while and made another bold attempt. But he failed to reach the grapes this time too. Forced to give up trying anymore, he walked away. Instead of owning his failure, he remarked with an air of dignity, “I thought those grapes to be ripe and juicy. But now I see that they must be quite sour.”
