"Following my father's death, I think it’s true that the house became my whole world. During the long period of mother's illness, the house often seemed so vast, so confidently REAL, that by comparison, I felt little more than a ghost haunting its corridors. Scarcely aware that anything could exist beyond those melancholy walls."
