What is the most precious thing in my life?

The most precious thing in my life is, of course, my family.
Grandpa: of course he is my grandfather but we are really like the best friend. He often told me about old days like his life during world war 2. I like listening to his talk. We used to play sports together when I was small.
Grandma: I learned many things from her like sewing, cooking, stock trading. I loved to go shopping to buy my clothes with her.
Father: He is working for my family without any complain. I know it is hard to support this big family. I respect him as a father, also as one man.
Mother: She is my ideal mother. Although our family is very big, she make box lunches for all everyday. I loved to chat with her after coming back from school.
Rieko: I often go shopping and see movie with her. One of my favorite clothes was given by her as a present.
Mayuko: She and I went to same high school and she was more clever than me. She is really good at science and I respect her.
Kazuki: Though we do not talk much now, we were like good friends when we were small. He is working hard now as a public officer.
Yusuke: He is still 14, so really cute!! He is the idol of our family. Everyone gives him whatever he wants.
