Speaking of kids in elementary school trying really hard to be adult:

Idk how common it is in the rest of the world, but in fourth grade, we had a subject that roughly translated to "Textile Work". It was about learning crocheting patterns and making basic little pockets or stuffed animals with googly eyes glued on top. Nobody really took it seriously, even less so because this was our last period for the day, and one of our last days before the upcoming spring holidays. Our teacher had given us some token task and left the room. We had opened the windows to let in some of our small town's silent spring breeze, only gently interrupted by the rustling trees encircling the old little church on a green hill just across the empty street.

Resident cool guy puts his boombox on the windowsill and plays a song about two people fucking ("Liebficken" by Sofaplanet if you want to google it). If you just discovered the word "fucking", this song got you fucking covered: Sometimes gently, sometimes rough, sometimes on your back, sometimes on all fours, and afterwards you two can look at the stars together. Those parts are all in the lyrics. The guy had it looped on cassette, apparently having decided that everything else was too immature now that he had seen the light and had brought us fire from the gods (or his big brother's bedroom at least).

He didn't have it on full volume, but in retrospect I've got to assume our teacher had heard it and just didn't care. We students didn't freak out either, but resident cool kid daring to go this high-profile someone with his smut did turn some 10-year-olds' heads. But mostly we were all just hanging around the windows trying really hard to look like we don't care about doing our crocheting patterns token assignment.
