In my opinion, every child should care for him parents. We have to do that, because : for the first, they gave us life; for the second, they raised us, also they supported us in difficult times of life. Some people think, that parents prevent us, teach us how we must to live, but I think that people are wrong. Parents don't prevent us, they just try to save us from mistakes and wrong choices. And in the end, I want to tell, that every child must to love, respect him parents and realize their requests.
