1) Every parent at least but once asked his or her child to help around the house. Children often don't want to do something, because they would rather  go for a walk or play computer games. 
2) But this is our home, we are a part of our house so we also should invest in its wellbeing and must work too! Cooking, shopping, washing, cleaning the flat are the things, teens should practise  while living in their family before they grow up and live on their own.
Our help is also a sign of respect and attention to our parents. Working together brings people more and more together. 
But why, so often, adults ask us to do something, although they can handle it themselves for a few minutes? Well, they ask us because they teach us to keep order in the house, and the ability to work. They do it because parents always do everything for the benifit of their child.
3) To conclude, I can confidently say that some help in doing the chores is a must for a teenager. Undoubtably, teenagers should help their nearest and dearest about the house. I think that those teens who help their parents to do something at home and have some domestic duties grow and become more responsible.
