ответ: I like Sunday because it is a day when I stay home with my family and don’t go to school. But I have to do some things about the house to help my parents. I usually do my room, clean carpets with vacuum cleaner. Sometimes I help mum to cook our Sunday dinner. And of course I wash dishes after it.

I think it is very important to help parents when you have free time. First, your parents are usually busy with lots of work. Second, while doing chores, you learn to do a lot of main things. We all must do everything to take care about ourselves and our close people. It is necessary in our life.
