WILLY: Why do you get American when I like Swiss?
LINDA: I just thought you’d like a change – .
WILLY: I don’t want a change! I want Swiss cheese. Why am I always being contradicted?
LINDA (with a covering laugh): I thought it would be a surprise.
WILLY: Why don’t you open a window in here, for God’s sake?
LINDA (with infinite patience): They’re all open, dear.

Death of a Salesman, Act 1. This exchange shows how Willy likes routine and hates change. It also demonstrates how Linda goes out of her way to make her husband happy, but he on the other hand doesn’t treat her well. When she changes his cheese and offers him American whipped instead of Swiss, she is shouted at by an uncompromising Willy.
