Buffy: It's my first day! I was afraid that I was gonna be behind in all of my classes, that I wouldn't make any friends, that I would have last month's hair! I didn't think there'd be vampires on campus. And I don't care.
Giles: Then why are you here?
Buffy: To tell you that... I don't care, which... I don't, and... have now told you, so... bye.
