When reading S.E. Hinton's The Outsiders, what might be a suitable short story or other literary work to study as a companion piece?
Although this novel has been around for several decades, it still resonates deeply with American students today, and it is not hard to see why. Although the names of the characters and their cliques may seem odd and hopelessly outdated (Greasers, Socs, Ponyboy, Sodapop), the themes of feeling alone, unwelcome, uninvited, and less "cool" than others still cause many teens an enormous amount of pain as the navigate the world of middle school, junior high, and high school.
I am going to suggest a couple of things that might be appropriate for your goals in reading/teaching this book. Although you requested items that are available online to copy, this first item probably is not, but I am also including a link below to an article on education.com that appears to be available and free to anyone.
The Courage to be Yourself: True Stories by Teens about Cliques, Conflicts, and Overcoming Peer Pressure. Edited by Al Desetta, M.A. with Educators for Social Responsibility.
