Once upon a time, there was a farmhouse beside a jungle, there on the farm were many grapes trees.
One evening a fox was passing through the firm house located beside the jungle and spotted a bunch of grapes hanging from over a lofty branch.
Seeing the grapes the fox’s mouth became full of water and the fox thought to eat the grapes.
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. This the fox tried so many times but failed to get the grapes.
Finally, giving up, the fox turned up his nose and said, the grapes are sour grapes not good for eating and walked away.
