"I've always known that the quality of love was the mind, even though the body sometimes refuses this knowledge. The body lives for itself. It lives only to feed and wait for the night. It's essentially nocturnal. But what of the mind which is born of the sun, William, and must spend thousands of hours of a lifetime awake and aware? Can you balance off the body, that pitiful, selfish thing of night against a whole lifetime of sun and intellect? I don't know."

In the end, it was the Sunday afternoons he couldn't cope with, and that terrible listlessness that starts to set in about 2:55, when you know you've taken all the baths that you can usefully take that day, that however hard you stare at any given paragraph in the newspaper you will never actually read it, or use the revolutionary new pruning technique it describes, and that as you stare at the clock the hands will move relentlessly on to four o'clock, and you will enter the long dark teatime of the soul.
