A young man does not like coming home from work. He lives with his wife and a young child in a small rented room. Their landlady is a grumpy and nosy old woman. She has a bad habit to enter, in absence of knock, the bathroom - an only room that the young couple can use in private. They solve family problems there, and the man is allowed to smoke there. The man is irritated by the curlers in his wife's head, it seems that their love is over. He is disappointed at work, too. After a long discussion, he admits to his wife and to himself that it was not her pregnancy that made him leave the university, the main reason was his incompetence to study. Eventually, kissing each other, they recall that they still love each other.
