Indeed, the only person he remains connected to is his dying mother, with whom he shares a tender, yet restrained relationship. The night before he is to return from leave, he stays up with her, exchanging small expressions of love and concern for each other. He thinks to himself, "Ah! Mother, Mother! How can it be that I must part from you? Here I sit and there you are lying; we have so much to say, and we shall never say it." In the end, he concludes that he "ought never to have come on leave."
