There's some kind of problem going on with my face, I've noticed. It's growing slowly more independent, attempting to make its own way in the world, heedless of the warnings of my brain.

Scenario: mid-lesson with student.

Face: Right, well, you work on that for a minute, and I'll just run to the bathroom, because...

Brain: BECAUSE? Why on EARTH would you say 'because'? BECAUSE WHAT? Walk away. Just walk out of the room. NOW.

Face: Because...

Brain: YOU DID NOT just do that. Walk. Away. You've already done irreparable damage to your credibility.

Face: Just because, okay?

Brain: Nice save, asshole.
