Is it possible that on some level, people want to believe that everything's going to get worse? That it's comforting to think that humanity is bad and every solution will just go wrong? Because that way, you're never responsible. You never have to take on responsibility for anything outside yourself and never have to grow up.

Fucking shit, cunt, cunt, cunt, cunt! Who the fuck are you speaking to? Who? Who? I'm talking to you huh? You fuck! Next time don't get in my fucking face! I just saw a fucking ghost and I gotta hear your crap? Get up! Get up! Fuck you then.

What is bravery, without a dash of recklessness?

GLaDOS: Oh, thank God you're all right. You know, being Caroline taught me a valuable lesson. I thought you were my greatest enemy, when all along you were my best friend.

Announcer: Caroline deleted.

GLaDOS: Goodbye, Caroline. You know, deleting Caroline just now taught me a valuable lesson: the best solution to a problem is usually the easiest one. And I'll be honest. Killing you? Is hard. You know what my days used to be like? I just tested. Nobody murdered me. Or put me in a potato. Or fed me to birds. I had a pretty good life. And then you showed up. You dangerous, mute lunatic. So you know what? You win. Just go.
