My, my, what a cold shoulder! And such uncouth apparel! Why, you haven’t even shaved! The unforgivable insult to a lady! But I forgive you. I forgive you because it’s such a relief to see you. You’ve stopped that polka tune that I had caught in my head.
– Tennessee Williams
A Streetcar Named Desire, Scene 9. Blanche is insulted by Mitch’s dressed down and unshaven appearance when he comes to see her. But she forgives him, because Mitch is the only one to save her sanity and stop the polka music she hears in her head. The music is linked to her guilt over her husband’s suicide and reflects her mental deterioration.
