I suppose I'd had, by the standards of that pre-permissive time, a good deal of sex for my age. Girls, or a certain kind of girl, liked me; I had a car-not so common among undergraduates in those days-and I had some money. I wasn't ugly; and even more important, I had my loneliness, which, as every cad knows, is a deadly weapon with women. My 'technique' was to make a show of unpredictability, cynicism, and indifference. Then, like a conjurer with his white rabbit, I produced the solitary heart.
