When the father dies, he writes, the son becomes his own father and his own son. He looks at is son and sees himself in the face of the boy. He imagines what the boy sees when he looks at him and finds himself becoming his own father. Inexplicably, he is moved by this. It is not just the sight of the boy that moves him, not even the thought of standing inside his father, but what he sees in the boy of his own vanished past. It is a nostalgia for his own life that he feels, perhaps, a memory of his own boyhood as a son to his father.
