After this he left the room much depressed, and watching his opportunity, for the merry party in the _salon_ who had gathered to greet him were still there drinking heavy white wine, he slipped through the back door to walk in the woods. These woods were lonely, but then they suited his mood. In truth, never had he felt more alone in his life. His father and he were utterly different, and estranged, and he had no other relatives. In friends he was equally lacking. Miss Ogilvy, whom he had begun to love, was dead, and a friend in heaven is some way off, although he did think he had heard her voice when he was so near to joining her. There remained no one save the Pasteur, of whom he was growing truly fond, so much so, that he wished that the old gentleman had been appointed to be his father according to the flesh. The rest of the world was a blank to him, except for Isobel, who had deserted him. Besides, some new sentiment had entered into his relations with Isobel, whereby these were half spoiled. Of course, although he did not altogether understand it, this was the eternal complication of sex which curses more than it blesses in the world; of sex, the eating fire that is so beautiful but burns. For when that fire has passed over the flowers of friendship, they are changed into some new growth, that however gorgeous it may be, yet always smells of flame. Sex being the origin of life is necessarily also the origin of trouble, since life and trouble are inseparable, and devours the gentle joys of friendship, as a kite devours little singing birds. These go to its sustenance, it is true, and both are birds, but the kite is a very different creature from the nightingale or the lark. One of the great advantages of matrimony, if it endures long enough, is that when the sex attraction, which was its cause, has faded, or practically died, once more it makes friendship possible. Perhaps the best thing of the little we have been told about heaven, is that in it there will be no sex. If there were, it is doubtful whether it could remain heaven, as we define that state, since then must come desires, and jealousies, and selfishness, and disappointment; also births and deaths, since we cannot conceive sex-love without an object, or a beginning without an end. From all of which troubles we learn that the angels are relieved.
