One's life, only oneself know

Marianne Borg: I saw you with your mother, and I was panic-stricken.

Professor Isak Borg: I don't understand.

Marianne Borg: I thought: That's his mother. An old woman, cold as ice, more forbidding than death. And this is her son, and there are light years between them. He himself says he's a living corpse. And Evald is growing just as lonely, cold and dead. And I thought of the baby inside me. All along the line, there's nothing but cold and death and loneliness. It must end somewhere.

Professor Isak Borg: I have liked having you about the house.

Marianne Borg: Like a cat.

Professor Isak Borg: A cat, or a human being.
