Bernardo: For what?
Riff: That's the way it's done, buddy-boy.
Bernardo: Ah, more gracious living. Look, every one of you hates every one of us and we hate you RIGHT BACK. Let's get at it.
Ice: Now you all better dig this, and dig it good! No matter who or what is eatin' you, man, you show it and you are DEAD. You're cuttin' a hole in yourselves for them to stick in a red-hot umbrella and open it, wide. Man, you wanna get past the cops when they start askin' about tonight? You play it cool. You wanna live in this lousy world? Play it cool.
Doc: When do you kids STOP?! You make this world lousy.
Action: We didn't make it, Doc.
Doc: Why do you kids live like there's a war on? Why do you kill?
Tony: I told you how it happened. Maria understands. I thought you did, too.
Doc: Maria understands nothing. Never again. There is no Maria.
Tony: ..Maria?
Maria: Tony!
Tony: I...I..I didn't believe hard enough.
Maria: Loving is enough.
Tony: Not enough here...they won't let us be.
Maria: How do you fire this gun, Chino? Just by pulling this little trigger? How many bullets are left, Chino? Enough for you? And you? All of you! You all killed him. And my brother. And Riff. Not with bullets and guns -- with hate! Well, I can kill too, because now I have hate. How many can I kill, Chino? How many -- and still have one bullet left for me?
