RE: Not a Teenager but...
I think my question was not "what is a teenager" and more "what is an adult." And it was a question in social theory. I ponder things like "is adulthood strictly defined by age, physical maturity, behavioral maturity?" and then I try to figure out at what point other people, or society as a unit, makes such distinctions. I especially wanted from the point of view of "teenagers," a category invented in the modern age by advertising companies defining a new target age group. What do they consider an adult, and at what point is it 'uncool' or 'creepy' to associate with one?
