My father asked me abruptly if it was raining outside. To be sure it was about to rain. Then he said to me, ‘Go home quickly. Be careful. I will lie down and rest.’ I was very surprised because he had long lived in the world where no one else besides himself live. He had no ‘others.’ I was no exception. It seemed that he had no emotion. He never found it strange that I was always with him in the daytime. It is said that Alzheimer’s disease is incurable. Nevertheless if a cure were possible it is not by regaining his memory he had lost but by being able to recognize others, which may be difficult but not necessarily impossible. Anyway even if his disease is incurable one thing is certain: I will take care of him as long as he lives. My father will be my father whatever happens.
