What if: it was discovered, whether before or after Aang unfroze, that benders of other elements, and indeed even non-benders, CAN learn to bend said elements with enough effort and devotion? (e.g. A born Water Bender who isn’t the avatar learns to Earth Bend, etc.)

Have you seen the last airbender show? The movie was a soulless mockery of it with absolutely no sense or real inspiration from its source material. If you haven’t seen the show, trust me, it’s more than more than worth the watch.

High School Tech Theatre Teacher. Many of the teachers in the theatre department at that school had somewhat of a reputation. This one, I felt at first, might’ve been unearned. She seemed genuinely good at her job, besides the occasional slip-up. During one class period, she explained to the class that she expects us to set up our big giant table and the chairs for it(It was a rather unfinished building specifically for the theatre department with no actual classrooms, so our classroom was actually just a square nook in a hallway.) before class began so we could get through lessons faster. Reasonable request, that’s fine, we were getting rather…nothing done for awhile because of how janky it was to have a classroom setting like that. That’s not necessarily her fault.
One class, though, there were some band students moving their instruments - talking cellos, saxophones, tubas, entire drumsets, and other big and/or fragile instruments and class materials - to the auditorium nextdoor through said classroom which was…just a hallway. Y’know, using the hallway as it’s supposed to be used, rather than as a classroom. We, as people with common sense, didn’t start moving around our heavy class materials likely to cause injuries just to make the path even narrower than it already was. Once class started, teacher RAILED at us for about a minute. She was clearly SEETHING as she ranted about how when she says to do something we do it. One student tried to explain our reasoning for the delay, even saying “There were other students moving heavy stuff through here. Why would we form a big block?” Her response?

“Why would you not?” I am not fucking joking, those were her exact words. She then interrupted him before he could respond and told him he was saying he didn’t care what she had to say and he was being disobedient. When he tried again to explain himself she threatened to send him to the principal.
This was not the only thing she did that proved to me she was a power-tripping removed who saw us students as her inferiors, but it was the one thing I just can’t get out of my mind because of just how absurd it was in the moment. The only funny part was that she didn’t even realize she was taking up MORE class time than we took setting up as she raved about such a petty issue because we apparently questioned her authority.

that isn’t the teachers fault.

The…the teacher was literally encouraging his punchable behaviour though.
