Buffy the Vampire Slayer, Season 1

Cordelia:
So, are you saying she's invisible because she's so unpopular?

Buffy:
That about sums it up.

Cordelia:
Bummer for her. 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.
