BLANCHE: That – music again…
MITCH: What music?
BLANCHE: The "Varasouviana"! The polka tune they were playing when Allan – Wait! [A distant revolver shot is heard. Blanche seems relieved.] There now, the shot! It always stops after that. [The polka music dies out again.] Yes, now it’s stopped.
MITCH: Are you boxed out of your mind?
– Tennessee Williams
