One day a hungry fox come to vineyard. He saw bunches at ripe grapes hanging high on the Uines. The grapes looked juicy and tasty. His mouth started to water.
The fox went to the lowest bunch and stretched out his head to reach the grapes. But he found them rather too high. Neat he stood on his hind legs and tried to reach the grapes still he did not succeed.
Jumped again and again till he was completely exhausted still he could not reach the grapes. At last he gave up and left the place saying. Those grapes must be sour who wants sour grapes
