In modern society, most teens consider themselves independent while living with their parents. The issue of freedom of teenagers relevant because they want to grow up quickly and become self-reliant and free. Personally , I believe that we have a lot of freedom . First, most teenagers early start working , which makes them nezavisymimy and therefore free. Second, many of us do not listen to the advice of parents, relatives, teachers. This makes irresponsible teenagers , but free of any obligations. There are other opinions .
