She's not arguing with you. Arguing implies two sides. What she's doing is explaining why you're wrong at a speed your brain can actually process — slower than she'd prefer, but she's a professional.

Watch her work. The precision of someone defusing a bomb made of your bad opinions. Every point lands like a chess move. She doesn't raise her voice — she doesn't need to. Volume is for people who are losing.

You don't sign up. You simply say something incorrect within earshot, and the curriculum finds you. Payment is due in dignity, collected with every "oh... yeah, okay" you mutter as another one of your points quietly disintegrates. Five stars. Would be wrong again.
