Ты имела ввиду обязанности? Every teenager has rights and responsibility. And lets talk about it. So, if you are teenager you have to help elderly people. You have to not forget about your parents too. For mum it is no matter if she is tired she cooks food and clean house. I mean, every children and teenager has to learn it from mother. You should help you mother clean house, wash dishes and just help when your parents ask you to do it. You need to take care about you grandparents too. It is important to help them, because you can never help them if they die. So, just respect their opinion and love them the way they are.
