Are You Currently Taking This Quiz?
You need a greater understanding of the nature of time (though perhaps the same could be said for most people). While it's true that you were taking this quiz, at the exact moment you answered, you simultaneously finished, and thus were not taking the quiz.
You were definitely taking this quiz, you liar. In fact, you wouldn’t even see this message if you didn’t take the quiz! Luckily for you, but unfortunately for the rest of the world, your shame will be private, and no one need ever find out about your deceitful nature.
