Erin: (in response to life advice from Miriam) But...

Miriam: Everything you say is "but". It's like you've built a wall of "buts" around you.

(Erin thinks hard for something witty to say.)

Erin: Sounds pretty stinky.

Miriam: Don't be cheeky!

.... Time passes .....

Erin: I know, I know. I'm behind a butt-wall. But the but's are true. I'm not full of shit.

Miriam: On the contrary! Your butt-wall is crack-full of shit!
