A mutually fulfilled sexual union between two people is the rarest sensation which life can provide. But it is not quite real. It stops when the telephone rings. Such a passion can be kept at its early strength only by adding to it either more and more unhappiness (jealousy, separation, doubt, renunciation), or more and more artificiality (drink, technique, stage-illusions). Whoever has missed this has never lived, who lives for it alone is but partly alive.
