“How can anyone believe that you can "learn" how to feel and learn how to express it? How can anyone teach another person how to laugh and how to cry? How to be cheerful and how to be sad? Teach them what pain is, and despair, and desire, and passion? Hate and love? How can anyone waste their own and somebody else's time with that idiocy? But far worse than the morons who think they can learn these things are the people who claim they can teach them. In the end, they teach bad manners. If one of their trained poodles sits down in public, he doesn't sit, he slouches - which is supposed to mean that his behavior is "natural." He or she scratches his or her head then picks his or her nose, which is supposed to mean that he or she has no complexes and acts very spontaneously. So this is what New York talk shows look like.”
