Adolescent years are different for everyone depending on the environment you were brought up in. For many middle class adolescents, they don't face many difficulties and are free to do as they please. For those in the lower class, the adolescent age requires someone to be more mature so they can help provide provide for the family, or they just don't have the income to do as the please. Vice versa the same for someone in a third world country at an adolescent age, the adolescent age for most americans would be non existent due to a teenager having kids and working at a young age, requiring them to be more mature than someone of a different status.
      The literature that we are reading tries to perceive adolescents in different ways. So far we have seen the effect of adolescents on poverty and middle class scale. The literature wants to put the reader in the shoes of the adolescent in the story and perceive the life that is lived, giving multiple views on adolescents. When multiple views are shown it is easy to see that adolescents almost has little to do with age, but environment and they stage of life where one can roam freely with little to no responsibilities.
