Jonathan Safran FoerI'm a vegetarian. You're a what? I don't eat meat. How can you not eat meat? I just don't. He says he does not eat meat. What? No meat? No meat. Steak? No... Chickens! No... And what about the sausage? No, no sausage, no meat! He says he does not eat any meat. Not even sausage? I know! What is wrong with him? What is wrong with you? Nothing, I just don't eat meat!
