Peter has a fight (打架) with one of his classmates. Then he goes to his grandfather and tells him his story angrily. "He is really bad, " the boy says, "and I hate (讨厌) him. "
The grandfather says, "Let me tell you a story. When I was a boy, I also sometimes hated others for what they did. "
As Peter listens carefully, the grandfather goes on. "There are always two tigers (老虎) inside my heart. One is good and kind. He is good with everything around him. But the other is bad and unfriendly. Even the smallest thing will make him angry. He fights with everyone all the time for no reason. He can't think carefully because he always hates others. It is difficult to live with these two tigers inside my heart. They both try to control(控制) me. "
Peter looks into his grandfather's eyes and asks, "Which tiger always controls you, grandfather?"
The old man says slowly and seriously (严肃地), "The one that I feed. I always feed the good and kind tiger, so I never hate others and seldom (很少) get angry now. "
