"What is your childhood trauma?!?!" Cordelia - Welcome to tthe Hellmouth
"Well, I like you. You're nice, and you're funny, and you don't smoke. Yeah, okay, werewolf, but...that's not all the time. I mean, three days out of the month, I'm not much fun to be around either." Willow - Phases
"You're a sheep. All you ever do is what everyone else does, just so you can say you did it first. And here I am, scrambling for your approval, when I'm way cooler than you are, 'cause I'm not a sheep. I do what I want to do, and I wear what I want to wear, and you know what? I date whoever the hell I want to
date. No matter how lame he is." Cordelia - Bothered, Bewitched & Bewildered
