Willow:  You dreamed about Angel again?

Buffy:  Third night in a row.

Willow:  What did he do in the dream?

Buffy:  Stuff.

Willow:  Oh! Stuff! Was it one of those vivid dreams where you could feel his lips and smell his hair?

Buffy:  It had surround sound. I’m just thinking about him so much lately.

Willow:  You two are so right for each other. Except for the, uh…

Buffy:  Vampire thing.

Willow:  That doesn’t make him a bad person. Necessarily.

Buffy:  I’m brainsick. I can’t have a relationship with him.

Willow:  Not during the day, but you could ask him for coffee some night. It’s the non-relationship drink of choice. It’s not a date, it’s a caffeinated beverage. Okay, sure, it’s hot and bitter like a relationship that way, but…

Xander:  What’s like a relationship?

Buffy:  Nothing I have.
