MASON: Heed his advice and stay on his good side. He’s like a volcano, George. He erupts and he spews lava and all the little villagers, they run around for their lives. But, you know, he stops, and you can go back to the safety of your own home.
GEORGE: How long is he gonna stay mad?
MASON: I’ve seen him stay mad for years. I’ve seen it, but it’s not like this pitbull mad, it’s like this disturbing, simmering, quiet rage mad. But he likes you, George. He’ll stay mad for less time.
GEORGE: Days? Weeks?
MASON: What’s the other one after that one?
GEORGE: Months?
MASON: Yeah, yeah, that’s the one.
