[alt text: a 4-panel comic by @introvertdoodles, which is titled "Not 'Appropriate'". The first panel depicts a child wearing a very creative and unique outfit, and their parent is pointing at them and saying, "You can't wear that to church." The child is replying, "Why? All my bits are covered." In the second panel, the same child and a grandparent are eating dinner at a dining room table, and the grandparent is saying, "You aren't excused until you eat everything on your plate." The child is replying, "Why? I'm full." In the third panel, the same child is holding a stuff animal, and a different parent is telling them, "You're too old to be carrying that toy around." The child is replying, "Why? The tag just says 'ages 3 plus.'" In the fourth and final panel, the same child is sitting across from a school principal in the principal's office. The principal is saying, "You can't argue with the teacher." The child is replying, "Why? He was wrong."]
Had an argument with a teacher in primary school that a piece of paper itself is a 3D object, whilst the drawings on it are 2D. I pointed to a ream of paper across the room and enquired how it could be that thick if the pieces were 2D. She gave me lunchtime detention.
A teacher gave us the definition of biotechnology in primary school, something like "using living organisms to make products or services".
I asked if ploughing a field with a horse-drawn plough is biotechnology and was told off for having a piss. It was a genuine question and I still don't know.
