A hungry fox---search for food---sees some grapes---cannot get at them---goes away saying,” The grapes are sour.”
It was a hot summer day. A fox was feeling very hungry. He went out in search of food. Soon he came to a garden. He saw some ripe grapes hanging down a vine. His mouth began to water. He jumped at them, but could not reach them. He jumped for the second time, but the result was the same. He tried again and again, but it was all in vain. At last he left the garden with a heavy heart. But, to keep up appearances, he said,” The grapes are sour and are not at all worth eating.
Moral: People pretend to dislike what they cannot get.
