GLaDOS: "Look, you're wasting your time. And, believe me, you don't have a whole lot left to waste. What's your point, anyway? Survival? Well, then, the last thing you want to do is hurt me. I have your brain scanned and permanently backed-up in case something terrible happens to you, which it's just about to. Don't believe me? Here, I'll put you on:"
Strange voice: Hellooooooooo!
GLaDOS: "That's you! That's how dumb you sound! You've been wrong about every single thing you've ever done, including this thing. You're not smart. You're not a scientist. You're not a doctor. You're not even a full-time employee! Where did your life go so wrong?"

What are you doing?

It’s dangerous to go alone! Take this.

This is your fault. I'm going to kill you. And all the cake is gone. You don't even care, do you?

Sofia Sartor: You mentioned a creed before. What is it?
Ezio Auditore: Nothing is true, everything is permitted.
Sofia Sartor: That is rather cynical.
Ezio Auditore: It would be if it were doctrine. But it is merely an observation on the nature of reality. To say that nothing is true is to realize that the foundations of society are fragile and that we must be the shepherds of our own civilization. To say that everything is permitted is to understand that we are the architects of our actions and that we must live with our consequences, whether glorious or tragic.

How about I read you a story? Once upon a time there were three little pigs. I'm emphasising the past tense because they all died. Just like you will. I really like the story.

I've got some advice about getting covered in the propulsion gel.... do not get covered in the propulsion gel.

All these science spheres are made of asbestos by the way, keeps out the rats. Let us know if you feel a shortness of breathe, a persistent dry cough or your heart stopping, because that's not part of the test. That's asbestos.

Bean counters said I couldn't fire a man just for being in a wheelchair. Did it anyway. Ramps are expensive.

What's true and what IS, aren't always the same.

I realize now that it will take time, that the road ahead is long and shrouded in darkness. It is a road that will not always take me where I wish to go and I doubt I will live to see its end, but I will travel down it, nonetheless. For at my side walks hope in the face of all that insists I turn back, I carry on and this...this is my compromise.

Everybody that I have cared about has either died or left me, everybody fucking except for you, so don't tell me I'd be more safe with someone else because the truth is I would just be more scared

All right, I've been thinking, when life gives you lemons, don't make lemonade! Make life take the lemons back! Get Mad! I don't want your damn lemons! What am I supposed to do with these? Demand to see life's manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I'm the man whose gonna burn your house down - with the lemons! I'm gonna get my engineers to invent a combustible lemon that'll burn your house down!

Endure and survive.

Ok. We need to lighten the mood.
