Nice post. I think that the main problem is that most people in their teen years don't really have very defined goals or objectives, oftentimes not even a hobby. This probably means that interactions with other teens will be based on more shallow elements. Start smoking because other teens smoke. Dress like Bieber or Kardashian because thats what other teens do. However, at this stage there is still no real common interests among them, which, in my opinion, is fundamental for more meaningful relationships. My two cents.
