Cordelia : "It's awful to feel that lonely."
Buffy : "Hmm. So you've read something about the feeling?"
Cordelia : "Hey! You think I'm never lonely because I'm so cute and popular? I can be surrounded by people and be completely alone. It's not like any of them really know me. I don't even know if they like me half the time. People just want to be in a popular zone. Sometimes when I talk, everyone's so busy agreeing with me, they don't hear a word I say."
Buffy : "Well, if you feel so alone, then why do you work so hard at being popular?"
Cordelia : "Well, it beats being alone all by yourself."

Giles : "You know, I... I don't recall ever seing you here before".
Cordelia : "Oh no. I have a life."
