Quote from Emily in Fight Face
Rory: Where did you get this, Grandma? Emily: I had your grandfather's secretary find me info on interacting with fellow prisoners. Rory: But we're not prisoners. We're just doing community service. Emily: They look like prisoners. Rory: Well, you know, sitting here in the jag staring at them is probably not going to help my popularity. Emily: Oh, you're right. That's on the list, too. Staring is bad. You shouldn't do it for more than one or two seconds. Rory: I won't. Emily: And they emphasize that you "keep your fight face at home." I'm guessing that's any sort of aggressive expression, whether you're staring at the person or not. Fight face, remember that.
