there lived a fox in a certain jungle. He was very hungry one day. He came out of his hole and began to move about in search of some prey. He happened to pass by a vineyard. After some time he saw big bunches of grapes hanging down the wall. His mouth began to water, and he decided to eat some. He jumped at them again and again, in order to catch them. But his effort were all in vain. However he wanted to conceal his shame and disappointment. He therefore said as he took his way,” these grapes are very sour. I am not, therefore, prepared to eat them.”
