And then she began to see the roofs: but that did not give her any qualms: only she asked what she was doing so high up, and became herself again. Work bored her. She persuaded herself that it stood in the way of her love: no doubt because her love had already become less ardent. But there was no evidence of that. They could not bear to be out of each other's sight. They shut themselves off from the world, and closed their doors and refused all invitations. They were jealous of the affections of other people, even of their occupations, of everything which distracted them from their love. Olivier's correspondence with Christophe dwindled. Jacqueline did not like it: he was a rival to her, representing a part of Olivier's past life in which she had had no share; and the more room he filled in Olivier's life, the more she sought, instinctively, to rob him of it. Without any deliberate intention, she gradually and steadily alienated Olivier from his friend: she made sarcastic comments on Christophe's manners, his face, his way of writing, his artistic projects: there was no malice in what she said, nor slyness: she was too good-natured for that. Olivier was amused by her remarks, and saw no harm in them: he thought he still loved Christophe as much as ever, but he loved only his personality: and that counts for very little in friendship: he did not see that little by little he was losing his understanding of him, and his interest in his ideas, and the heroic idealism in which they had been so united.... Love is too sweet a joy for the heart of youth: compared with it, what other faith can hold its ground? The body of the beloved and the soul that breathes in it are all science and all faith. With what a pitying smile does a lover regard the object of another's adoration and the things which he himself once adored! Of all the might of life and its bitter struggles the lover sees nothing but the passing flower, which he believes must live forever.... Love absorbed Olivier. In the beginning his happiness was not so great but it left him with the energy to express it in graceful verse. Then even that seemed vain to him: it was a theft of time from love. And Jacqueline also set to work to destroy their every source of life, to kill the tree of life, without the support of which the ivy of love must die. Thus in their happiness they destroyed each other.
