l attended my grand son's class yesterday. He was very selfish when he came to my home in Japan, so I am worrying his future. But he is very nice boy knowing him in the USA. l became true friend with him. I realized that if we want to know a person, we should go to his home ground. I watched my picture with him, it was a very old person. I recognized that l am very old although l never think so. I must think about my work.
