(This is friendly conversation btw, I don't want this to come off as argumentative) I guess being an a-typical teenager I disagree, Phlex. I feel the whimsy of childhood ends in high school. Recently on the news you'll frequently hear a broadcast about how high-schoolers are pushing themselves too hard. I personally don't work because I literally think I would go out of my mind, but.. I take AP and honors classes, I have (legit, non-PE) extracurriculars, I volunteer, I hold leadership positions. I won't complain about the responsibility that I have, because I've brought it upon myself, and it's ok, but no one helps me. My parents don't baby me and do everything for me. I don't underestimate what they do for me, but when it comes to real life, I'm responsible for myself. And that's chaotic as well.
I won't dispute that as a parent, yes that's definitely more hectic than any other period in your life, but I don't think an average adult really is much more busy than a (hardworking) student. We have full-time jobs, it's called school. I don't have slack-off classes. I work all day at school. Then I go home and work more.
Sorry for the mini-rant, slightly off-topic as well; it just gets tiring to hear how easy we have it when I push my self to the max until winter/summer break, and then I crash, without fail every semester. Sorry! :/
