There is an old tiger in the forest  . He doesn't want to look for   food now. He often lets other animals get him some food to eat. One day, he sees a monkey   and says,"I am hungry, monkey. Go and get me something to eat.""I can't do that now, tiger." the monkey says,"There is another tiger over there . He doesn't let me get anything for you to eat. I am afraid of   him." "What?" says the old tiger. "Take me to the tiger. I want to talk to him." The monkey and the tiger go to the bridge  over the river . "Now look down at the water." says the monkey. "Do you see the tiger?" "Yes, I do." says the old tiger. "Let me eat him." Then the tiger jumps  into the river. Why do other animals get food for the tiger?
Because they are afraid of him. Because only they can find some food. Because they are his friends. Because they like to do that.
