"Sleep" Horses, yes. Dogs, old ones especially. People of course. Even trees. Planets, atoms, do not. Bacterium, virus? Unlikely. Pens sleep most of the time, but awaken quickly -- one shake or a few dry strokes suffice. A fire sleeps by dark, a cat by daylight, each curled in a warming circle. A rock lies still or tumbles, but cannot sleep. Does the wool sleep along with its sheep? The hoof with its cow? The finger sleeps and the ring does not -- what of the vow? A woman touched by a man pretends, sometimes, to sleep, for the pleasure of letting him think that she awakens. After, her thighs sleep differently than before. Sometimes the heart goes sleepless or sleeps for years; sometimes the mind. I have tried to talk with my sleep, to ask it politely for this or that, but it only averts its gaze. "Go away," it says, and, "Leave me alone." As if without me it could be anything at all. Still, it knows who is slave, who master. And so I lavish on it goosedown and soft cotton, offer it sweetened milk or wine, tuck it into warm blankets under a window opened just an inch. Some speak of entering sleep, but it is sleep that enters us, as a farmer, familiar, confident, enters his field. Night after night it tills and waters, so that at times we awaken buoyant, other times in inexplicable grief. And though the child who refuses to sleep is right perhaps to be inconsolable -- begging more time, clutching her bear to her cheek -- she too will finally agree. Joining the silent magpies and tough-skinned conch and saguaro; the swaying mule deer, suspended pipefish, and deep-sighing maple -- all who, drifting, distal, quilt the drowsy night-song of the mortal.
