I have changed a lot. I used to be short and had a large build. But now I am much taller and thinner. I was lazy before and I didn't like doing housework. But now I am a hardworking person and I often help my parents do some housework, such as, cleaning the room, washing the dishes, doing the shopping and so on. I think doing the housework can help me grow up and to be indepent. I work hard at my study so I can get better grade than before. I think I am becoming lovely, energetic and easy-going.
