Today is Sunday.At 8 P.M.,I am doing my homework when my father and grandfather are playing chess.At the same time,my sister is writing postcards to her friends,while my mother and grandmother are watching TV.My brother is a hardworking boy. And he is reading books in his room.I think he is the most diligent boy in his class.In a word,we have a good time.
