Tell the others right away, “No, I don’t want to watch TV!” Raise your voice—they won’t hear you otherwise—“I’m reading! I don’t want to be disturbed!” Maybe they haven’t heard you, with all that racket; speak louder, yell: “I’m beginning to read Italo Calvino’s new novel!” Or if you prefer, don’t say anything; just hope they’ll leave you alone. Find the most comfortable position: seated, stretched out, curled up, or lying flat. Flat on your back, on your side, on your stomach. In an easy chair, on the sofa, in the rocker, the deck chair, on the hassock. In the hammock, if you have a hammock. On top of your bed, of course, or in the bed. You can even stand on your hands, head down, in the yoga position. With the book upside down, naturally."
