“The rest of the story, to Grand's thinking, was very simple. The common lot of married couples. You get married, you go on loving a bit longer, you work. And you work so hard that it makes you forget to love. As the head of the office where Grand was employed hadn't kept his promise, Jeanne, too, had to work outside. At this point a little imagination was needed to grasp what Grand was trying to convey. Owing largely to fatigue, he gradually lost grip of himself, had less and less to say, and failed to keep alive the feeling in his wife that she was loved. An overworked husband, poverty, the gradual loss of hope in a better future, silent evenings at home, what chance had any passion of surviving such conditions? Probably Jeanne had suffered. And yet she'd stayed; of course one may often suffer a long time without knowing it. Thus years went by. Then, one day, she left him. Naturally she hadn't gone alone. "I was very fond of you, but now I'm so tired. I'm not happy to go, but one needn't be happy to make another start." That, more or less, was what she'd said in her letter.
Grand, too, had suffered. And he, too, might, as Rieux pointed out, have made a fresh start. But no, he had lost faith. Only, he couldn't stop thinking about her. What he'd have liked to do was to write her a letter justifying himself. "But it's not easy," he told Rieux. "I've been thinking it over for years. While we loved each other we didn't need words to make ourselves understood. But people don't love forever. A time came when I should have found the words to keep her with me, only I couldn't.”
