There’s nothing like a really good, really tricky would-you-rather question to test the content of a person’s character. I especially like to bust them out at parties. “I like your shirt,” I might say to a person I just met. “By the way, would you rather know when you’re going to die, or how you’re going to die?” (If they’d rather know when, I cut the relationship off right then and there. I don’t need to be hanging around with lunatics who would rather live each day counting down to the moment they inevitably shuffle off this mortal coil.)
Since would-you-rather questions are so illuminating, I think it’s possible to guess a person’s Hogwarts house based on how they respond to them. It’s not an exact science, except yes, it totally is. I don’t care if you think you’re a Slytherin; if the quiz says Hufflepuff, you’re a Hufflepuff now. End of story, thank you for your time.
