“I knew she loved sushi because it was neat and easy to eat on the go. I knew she preferred double cheeseburgers when she was on her period and steak, medium rare, at client dinners unless her client was vegetarian, in which case she ordered soup and salad. She liked her wine white, her coffee black, and her gin with a splash of tonic. I knew all of these things because despite her assumption that I paid attention to no one except myself, I couldn’t stop noticing her if my life depended on it. Every detail, every moment, all filed and categorized in the Sloane cabinet of my mind.”
