When we talk about how teenagers are getting worse and worse now, most young people don’t agree. Teenagers always say they are growing up. They can have part-time jobs. They can drive cars. And they can even get married when they’re a little bit older.
Their parents say, “Our children are very good. They like pop music, but they play it in their own rooms. They help in the house. You know they feel bored sometimes because there’s nothing interesting in the neighborhood, no clubs and no sports. They have nothing to do.
A teacher says that he believes most young people are very kind. He thinks that it’s not bad for young people to like loud music because it can give them lots of energy and make them feel excited .Also, a lot of young people work very hard at school, and they can get good jobs later.
Lewis, a sixteen-year-old boy said, “I have passed all my examinations, but I can’t get a part-time job because older people always think I’m lazy.”
In my opinion, a lot of teenagers are very kind. They belong to community work groups. They help old people, and they also volunteer in local hospitals or primary schools to help look after the sick people and younger students.
