An old tiger lives in the forest. He doesn't want to look for food. He often asks other animals to bring him something to eat. He sees a monkey and says, "I'm hungry, Monkey. Go to the village and bring me a fat pig." "Oh, Tiger," says the monkey. "I can't do that now. There is another tiger over there. He also wants a fat pig. He doesn't let me get anything for you to eat. I'm afraid of him." "What?" cries the old tiger. "Show me the tiger. I will talk to him." "Come with me," says the monkey, "Now look down at the river," says the monkey. "Can you see the head, the white teeth and the big green eyes of the tiger?" "Yes, I can," cries the old tiger. "I will eat him up." With these words, the tiger jumps into the water and dies(死亡).
The tiger is old.
