I appreciate your good nature in taking the time to engage in this silliness but I have a hard time believing your high school teacher or anyone else taught you that. The wikipedia page on it:

"In English writing, quotation marks are placed in pairs around a word or phrase to indicate:

Quotation or direct speech: Carol said "Go ahead" when I asked her if the launcher was ready. Mention in another work of a title of a short or subsidiary work, like a chapter or episode: "Encounter at Farpoint" was the pilot episode of Star Trek: The Next Generation. Scare quotes used to mean "so-called" or to express irony: The "fresh" apples were full of worms."

Even 'direct speech' is at odds with 'verbatim quote' and that's the first thing there. Direct speech can be completely made up.
