OPERATOR’S VOICE: Standish Arms, good evening!…Ringing Mr. Loman for you!
WILLY: I’m not there, stop it!
BIFF (horrified, gets down on one knee before Willy): Dad, I’ll make good, I’ll make good. (Willy tries to get to his feet. Biff holds him down.) Sit down now.
WILLY: No, you’re no good, you’re no good for anything.
BIFF: I am, Dad, I’ll find something else, you understand? Now don’t worry about anything. (He holds up Willy’s face.) Talk to me, Dad.

– Arthur Miller

Death of a Salesman, Act 2. Willy Loman’s failures as a good father and husband are on full display here. He yells at an imaginary telephone operator during a flashback memory of when schoolboy Biff found him with another woman in a Boston hotel. The adult Biff moves to calm the irrational Willy down. He doesn’t want to disappoint his father after his failure to get a loan from Bill Oliver to go into business. He assures Willy that he will "make good," but Willy dismisses Biff as a "no good." The scene represents Willy’s betrayal of his wife Linda, the guilt he carries with him, and the damaged relationship he has had with Biff since he discovered the affair. Willy proves to be a terrible father, as well as a terrible husband.
