BIFF: Yeah, but he doesn’t mean anything to you. You could help him – I can’t. Don’t you understand what I’m talking about? He’s going to kill himself, do you know that?
HAPPY: Don’t I know it! Me!
BIFF: Hap, help him! Jesus…help him…Help me, help me, I can’t bear to look at his face!

– Arthur Miller
