You arrive as the sleep ward is preparing for lunch. A pair of nurses moves from one cluster of patients to the next, recording responses on a clipboard. Their standard-issue scrubs are immaculately clean, but rumpled. Other nurses either sit behind a desk or move about attending to various duties. The patients all wear knee-length gowns with a checkered pattern, like a simulacrum of pajamas. In lieu of shoes, they wear socks with rubber grips on the soles. None have watches, and there are no visible clocks. Unease and exhaustion mix in the air like competing perfumes, condensing into a steady drip of idle chatter. The nurse at the seat of the desk nearest the door turns in his office chair to look at you. With a faint Southern drawl coloring his words, he asks you to please hand over any watches, cell phones, or other electronics.
