A Quote from Portal 2
GLaDOS, Announcer
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. The surge of emotion that shot through me when I saved your life taught me an even more valuable lesson - where Caroline lives in my brain.

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.
GLaDOS starts Chell's elevator moving up; she laughs softly
GLaDOS: It's been fun. Don't come back.

Did you feel that? That idiot doesn't know what he's doing up there. This whole place is going to explode in a few hours if somebody doesn't disconnect him. I can't move, and unless you're planning to saw your own head off and wedge it into my old body, you're going to need me to replace him. We're at an impasse.
You know what I have too many of around here? Monitors. I was just thinking earlier today I wish I had fewer monitors that were working. So you're actually helping me by smashing them.
It's not like I have hordes of replacement monitors just lying around back here in the old warehouse that I can just wheel out and bolt back on. I didn't order in loads of spare monitors thinking some crazy woman was going to go around smashing them all. Sorry if that's my fault. Sorry if I didn't have the forethought to think "oh she might go crazy one day and smash all the monitors instead of just getting on with things". Sorry I didn't think of that.
