A conversation between any two parts of your body. Mine happen to be in conflict but two that are in harmony would also work, I suppose.
Legs: So let me get this straight...
Brain: Here we go.
Legs: Last night we ran ourselves to exhaustion at ultimate.
Legs: For like two and a half hours. Real, real tired. Like I could barely get us up that tiny hill after the game.
Brain: I recall.
Legs: And now this morning you expect me to bike us halfway across the city, then back again.
Brain: Uh huh.
Legs: On one night's rest. And we hate mornings. Are you failing to see the problem here?
Brain: Listen, if we keep this up you'll be in great shape and this sort of stuff will just get easier and easier.
Legs: Ha ha, that's a good one... if we keep this up... that's cute. It's like you actually expect me to get you out of bed tomorrow morning.
Brain: It'll be fine, we'll rest this afternoon and tonight, get a good sleep and then we can get back at it tomorrow!
Legs: Who the hell put you in charge anyway?
Brain: Hey, nobody else wanted to take charge. Well, besides that guy that hangs out with you but I think we can agree his judgment is atrocious.
Legs: A throw what?
Brain: Bad. Completely lacking rational thought.
Legs: Then why do you let him take charge every now and again?
Brain: We'll have to discuss that later, time to hop on the bike!
Legs: I hate you so much.
