Krebs spends his days in a state of listlessness; he does not want to become involved in the intrigues and politics of his town's life. Because he finds things at home "too complicated," he withdraws into his room for most of his time.
With the title as a double entendre--the soldier is in the home of his youth, and the place is like a soldier's home, a lonely place for injured or retired soldiers--Krebs, who is somewhere in between the innocence of youth and the disillusions of age, does not feel as though he belongs at home any more. Krebs finds that he cannot really return to this home of his youth and resume his old life; too much has happened to him, and he is no longer the same person.
A distaste for everything that had happened to him in the war set in because of the lies he had told....he lost everything.
Krebs does not want to be involved with anyone. He would like to have a girl, but he decides "it was not worth it." So, he merely goes to town to look at the girls. Besides, they are not in the same world as Krebs finds himself. He is changed by the experience of war, changed by the lies he has had to tell.
