I'm not sure if my horror story is better or worse.
My HS geometry teacher could tell whether or not my (double-column) geometry proofs were correct or not.
But she refused to give me credit when I gave proofs, which she admitted were correct, of theorems proved in our book, if my proof was different from the proof in the book---saying "The man who wrote the book is a mathematician, and he gave that proof for a reason. You aren't a mathematician, so you must use his proofs. When you're a mathematician, you can use whatever proofs you want to."
Fortunately, I could tell whether or not *she* was correct. But, now that I am a mathematician, I do use whatever proofs I want to.
