The ballroom at the St. Jude Community Center smelled like expensive lilies and cheap champagne. It was 7:42 in the evening, and the DJ had just finished a slow song that nobody had danced to. I was sitting at table four with my sister Linda, watching the way the light caught the sequins on Sandra Price’s dress. She was wearing champagne satin, a color so close to off-white that it made my teeth ache.
