Good Girl Gone Bad

This post will be short, though I'd like to come back and examine this topic further later. I have been constantly amazed this year by the number of my good friends who are girls that have started engaging in "sketchy" activities of various sorts. (Note: this applies to guys too, but I've noticed it more in my friends who are girls) Also, it seems that many of these girls fake an innocence to the outside world, yet secretly are proud of what they're doing and who they've become. Now maybe the fault lies with society that creates a double standard, or with parents who push their children to the edge of rebellion; maybe all teenagers are like this and I'm just naive, but still I notice a recurring theme of "good girls gone bad". Some can hide it well; others can't, but beneath it all beats the same desire to break the mold Country Day has told them that they fit, to rebel against the instruments or sports or art activities their parents signed them up for when they were six, and to assert their independence through bad-assness (I know that it's not a real word, but its appropriate here to capture the scope of both dubious morality and secret pride). I could list specific examples, but for the sake of privacy I won't, though my argument does seem a bit flat without them. And so I wonder, as we grow up, do some of us seek to assert independence through a secret rebellion (most parents/adults don't know the girls engage in the behavoirs that they do); and if the rebellion is secret, is it really rebellion at all or actually a submission to the will of adult society that says that girls must be innocent and to teenage society that praises edginess?
