"'But how can you stand it - just going on and on?' It is not easy sometimes - and some of us do give up, but that is a crime, because there is always chance. And it's not quite so monotonous as you think. Each transfer makes a difference. You feel as if the world had become a different place then. The spirit rises in you like sap in spring. . . . And those glands you think so much of are not entirely without effect, because you are never quite the same person with quite the same tastes. Even in one body tastes can change quite a lot in one lifetime, and they inevitably differ slightly between bodies. But you are the same person, you have your memory, yet you are young again, you're hopeful, the world looks brighter, you think you'll be wiser this time. . . . And then you fall in love again, just as sweetly and foolishly as before. It's wonderful - like a re-birth. You can only know just how wonderful if you have been fifty and then become twenty.' 'I can guess,' I said."
