I didn't have time to find a proper Halloween costume, so I improvised. With a white t-shirt, a low-cut black minidress with long sleeves and a hemline that shot skyward when I bent, a white headband, a black scarf that covered my hair, perilously high heels, and a necklace borrowed from a roommate with the Christ in agony, I made a passable mockery of a nun. My boyfriend, lover, dom, who was completing a residency in internal medicine at the time, dressed in a hospital gown as a patient.
