WILLOW: It's simple, really. See, 'The bisector of a vertex is the line that divides the angle at that vertex into two equal parts.'

XANDER: It's like a big blur, all these numbers and angles.

WILLOW: It's the same stuff from last week. You had it down then.

XANDER: Why do I need to learn this?

WILLOW: 'Cause otherwise you'll flunk math?

XANDER: Explain the part where that's bad.

WILLOW: You remember, you fail math, you flunk out of school, you end up being the guy at the pizza place that sweeps the floor and says, 'Hey, kids, where's the cool parties this weekend?' We've been through this. Do you have a headache? (reaches up to him)

XANDER: (shakes her off) Yeah, and I think I know what's causing it. (throws his geometry book into the trash) Ah! That's better, it goes right to the source of the pain.

WILLOW: Xander...

XANDER: Look, forget it, okay? I don't get it. I won't ever. I don't care. (storms off)

WILLOW: We can finish this another time.
