WILLY: Will you let me talk?
BIFF: Don’t yell at her, Pop, will ya?
WILLY (angrily): I was talking, wasn’t I?
BIFF: I don’t like you yelling at her all the time, and I’m tellin’ you, that’s all.

– Arthur Miller

Death of a Salesman, Act 1. The demeaning way Willy talks to his wife and constantly shouts at her to keep quiet provokes Biff’s ire.
