"Human relationships didn't work anyhow. Only the first two weeks had any zing, then the participants lost their interest. Masks dropped away and real people began to appear: cranks, imbeciles, the demented, the vengeful, sadists, killers. Modern society had created its own kind and they feasted on each other. It was a duel to the death--in a cesspool. The most one could hope for in a human relationship, I decided, was two and one-half years."
