When the donkey saw him approaching he said: “You cannot eat me, I have a passport.”
“What’s a passport?” asked the wolf, puzzled.
“Come and stand behind me,” said the donkey, “I’ll show you.”
The wolf, intrigued, went and stood behind the donkey. He was wondering if perhaps the donkey’s tail was the passport when he received such a kick on his face that two teeth shot out of his mouth.
While he lay on the grass, dazed, the donkey made good his escape.
Moral : You may need to go along with your enemy sometimes, be aware then.
