How to learn not to talk about? Elementary. In order to learn to run, not run. To learn how to swim, you swim. To learn how to talk about what is not, it is necessary to talk not about anything. When a woman looks at you, and you tell her about Kavko clobbered, about Sartre and about Marie Curie Sklodowska, she thinks "a zamorochenny dude as he cockroaches in the head, he's tired of me." That's the boys who talk about theoretical physics, the practical chemistry, computers put the label "nerd." A boring strain. This violates the basic principle of "not strained!".
