My Spanish teacher put me and two other classmates in detention for failing a test. His rationale was we had "clearly" not studied hard enough.
This burned into my brain "if I fail, it's because I didn't try hard enough, and I should be punished for it".
Still learning to unlearn that to this day.

What teacher got on your last nerve in grade school/college, and what did they do that earned a permanent spot in your memory?
