I had a friend who, at a campfire discussion that turned to extinct animals, asked “So what’s the deal with unicorns? Are they actually fully extinct now or just endangered?” As we stared at him silent and open-mouthed, he very clearly realized for the first time in his life that unicorns were make-believe and he had just made a total idiot of himself. Watching this play out on someone’s face in real time is a memory I’ll always cherish.
