Allow yourself to be overwhelmed by sleep. At any time and in any place. In a park, at a desk, in a moving automobile. Beside a river. Awaiting a bus. In the middle of the floor or in a corner by the window. At the dinner table—especially at the dinner table. Maybe smile a little bit at anyone around, as you catch yourself drifting off. But then, simply let your face fall forward, pull your arms up around it, and go to sleep.
