Rambo

John Rambo: Why'd you come back?
Sarah: Waiting for you.
John Rambo: I told you before, I can't help you.
Sarah: Well we need to go and help these people, we're here to make a difference, we believe all lives are special.
John Rambo: Some lives, some not.
Sarah: Really? If everyone thought like you, nothing would ever change.
John Rambo: Nothing does change.
Sarah: Of course it does! Nothing stays the same.
John Rambo: Live your life cause you've got a good one.
Sarah: It's what I'm trying to do!
John Rambo: No, what you're trying to do is change what is.
Sarah: And what is?
John Rambo: Go home.

Brilliant.
