The wolf and the goat
A hungry wolf was out searching for a meal. He saw a goat feeding on grass on top of a high cliff. The wolf wanted to get the goat to climb down from the rock. «Excuse me, dear Goat,» he said in a friendly voice. «It is very dangerous for you to be at such a height. Please, come down before you hurt yourself. Besides, the grass is much greener down here. Take my advice, and please come down from that high cliff.» But the goat knows too well the wolf's habits. «You don't care if I eat good grass or bad. What you care about is eating me.»
