I def had some weird experiences like this in school too, though not as extreme. I had a teacher once give me a zero on an exam because I used greater than and less than symbols to describe two lines intersecting. She thought I did them all backwards. Normally I’d be too shy to push back but zero on an exam was pretty extreme so I went to discuss one on one and she basically called me dumb saying I don’t know how the symbols worked (this was like 9th grade, I def did and was pretty alarmed she didn’t). Finally she said fine, she’ll go ask a math teacher to come explain to me in front of the class if I’m so smart. She left, was gone for like ten minutes, and came back super upset. Slams the paper on my desk in front of everyone and says something like ‘fine I guess you want an A now?’. Was traumatizing. But was actually a huge teaching moment for me in that I stopped seeing teachers as things/concepts, and started seeing them as people. Same as me/my classmates/some random on the street. No one has this shit figured out. I also realized I never wanted the experience she just had, and learned to always hedge my opinions. It looks like, I think, it seems to me, etc. Has saved me from looking stupid but also encouraged those that I teach to question my dumb shit. But yeah. Teachers are just people, have you met people?
Side note my math teacher was extra nice to me that afternoon - I also learned that the teachers don’t necessarily like each other either. Apparently I had helped score points for the ‘not batshit insane’ crew
Units are weird. I just say one orbit
