You've decided to interview a local police officer on your paper about law enforcement and race, but you don't know how to cite a personal interview in your works cited page. You decide to send your teacher an email asking him how to cite this. In his reply, he simply tells you to look it up$.$ Why won't he tell you the answer?

Your instructor doesn't know the answer.

The point of MLA isn't to memorize all of the answers, but to know how to find the answers you need. If your teacher gives you the answer, you don't learn much.

He wants you to find out, on your own, that MLA doesn't allow you to use personal interviews in an academic paper.
