I was definitely like Kid B. My precalculus teacher once asked me, in front of the whole class, how many assignments I’d have done out of 10. To which I answered honestly with 2, making everyone laugh.
My trigonometry teacher was convinced I was cheating on tests since I barely did any homework, and had me take a test alone in front of her to prove I wasn’t. I did well enough that she believed me and stopped questioning it, fortunately.
Also had a teacher scold me one on one in elementary school over not doing homework, making me cry. I’m sure she thought she was helping, but all that accomplished was making me feel bad.
Didn’t figure out I had ADHD until my 30s. Hopefully things will keep getting better for kids as knowledge and awareness expand.
