There were approximately twenty-five people milling around the door and the front of the classroom, but I immediately recognised Julie, the convenor, from Gene's description: 'blonde with big tits'. In fact, her breasts were probably no more than one and a half standard deviations from the mean size for her body weight, and hardly a remarkable identifying feature. It was more a question of elevation and exposure, as a result of her choice of costume, which seemed perfectly practical for a hot January evening.
