You walk or you do not walk. You sleep or you do not sleep. You walk down your six flights of stairs, you climb back up again. You buy Le Monde or you do not buy it. You eat or you do not eat. You sit down, you stretch out, you remain standing, you slip into the darkened auditorium of a cinema. You light a cigarette. You cross the street, you cross the Seine, you stop, you start again. You play pinball or you don't.
