“How well do you know Harry Potter and the Chamber of Secrets?” is a rhetorical question, actually, with the unspoken rhetorical answer being “better than I know my entire self.”
Look, I’ll level with you here: we like our readers to know things. It reflects well on us if you do. But not things like how to change a tire or how to find the hypotenuse of a triangle or what the stock market even is, because those things will just slow you down in life. I’m talking Harry Potter trivia. Obscure Harry Potter trivia, the kind that would simply baffle your basic garden-variety rube. But you? You’ve read the books back to front. You eat, breathe, and sweat Harry Potter. I can see it. I can feel it. You’re destined for greater things.
