Buffy:  Uh, Hi! Willow, right?

Willow:  Why? I-I mean, hi! Uh, did you want me to move?

Buffy:  Why don’t we start with, ‘Hi, I’m Buffy,’ and, uh, then let’s segue directly into me asking you for a favor. It doesn’t involve moving, but it does involve hanging out with me for a while.

Willow:  But aren’t you hanging out with Cordelia?

Buffy:  I can’t do both?

Willow:  Not legally.
