Nate: Why do you treat me like shit all the time, Brenda?
Brenda: Because I've had a really fucked-up life and I need sarcasm to hide how ridiculously miserable I am.
Celeste: You ever been with a woman?
Officer Keith Charles: Of course.
Celeste: I don't get fucked in the ass.
Officer Keith Charles: That makes one of us.
Brenda: The future is just a fucking concept that we use to avoid living today.
George Sibley: I've made a lot of enemies through the years. You take the backstabbing world of academia, throw in a controversial field like geology and you've got real trouble.
Claire: Geology is controversial?
George Sibley: Oil, Claire. Oil.
Claire: Well, isn't it comforting to know that being miserable is still better than being an idiot?
Claire: You know, at first I was worried, but now I'm just pissed.
Answer: Nate actually say "You can't take a picture of this, it's already gone." It's kinda hard to explain, but he's referring to the fact that the moment Claire wants to take a picture of is over already, and she can't take a photo of it, just a different, lesser moment.
