16-year-old here. My experience is probably markedly different from most teenagers in the US (I'm an immigrant who goes to a competitive school full of other immigrants) but I find that, for the most part, this article hits the nail on the head. High School is nothing like the usual media portrayal - I've never heard anyone even talk about a party, nobody's doing anything stronger than weed, nobody's fucking or even…
That's easy to explain: You don't have to talk about these things anymore, because of IM & co.. It's all still happening, but it's easier to hide it from the "dweebs". I've seen both sides, and it's really surprising how well this unwritten system works. At best you realize a few years or decades later.
