When I finally got a career going, I was most disappointed by how high school cliques and rivalries never went away, they just got shifted into adult work places and seemed to get more aggressive and petty.
Working at a bigger construction firm, the competition and rivalry between people who weren't even competing for raises or promotions was just odd, especially from the women in the office, they all hated each other's guts like they were trying to steal each other's husbands or something.
I like the idea that a personality doesn't really change much over time, but maybe just gets more refined and delineated. So your anxieties at 16 would probably be the same ones you feel at 50, more or less.
Completely contradicts the "common sense" theory that as you grow up, you start looking back at your past problems as trivial and your teen issues as laughable. Yes, maybe you didn't have to pay your rent and bills back then, but one way to look at is that "it's just a detail". In the big picture, you're still pretty much the same person with the same problems, insecurities, and worries.
I don't know, just my two cents.
I so love this comic. It's the perfect antidote to seeing the same trite adolescent themes played over and over in web comics.
Teenage anxieties: "Will I ever truly be content?"
Adult self: "Yup, psychiatric drugs work after a while. You get to be one of the lucky ones."
Adult anxieties: "But hey, now you actually *don't* want to die, so have fun with fear of death!"
I still have my old diaries and it breaks my heart to see how much pain I was in then between boys and bad friends and my own stupidity. I wish I could go back and tell myself to just chill the fuck out and also apply for some scholarships cuz *damn*
