A story from Mr.Murakami

A cat met up with a big male rat in the attic and chased him into a corner. The rat, trembling, said, "Please don't eat me, Mr.Cat. I have to go back to my family. I have hungry children waiting for me. Please let me go." The Cat said, "Don't worry, I won't eat you. To tell you the truth, I can't say this too loudly, but I’m a vegetarian. I don't eat any meat. You were lucky to run into me." The rat said, "Oh, what a wonderful day! What a lucky rat I am to meet up with a vegetarian cat!"

But the very next second, the cat pounced on the rat, held him down with his claws, and sank his sharp teeth into the rat's throat. With his last, painful breath, the rat asked him, "But Mr Cat, didn't you say you're a vegetarian and don't eat any meat? Were you lying to me?" The cat licked his chops and said, “True, I don't eat meat. That was no lie. I'm going to take you home in my mouth and trade you for lettuce."
