Rick.-... It was La Belle Aurore.
Ilsa.-How nice, you remembered. But of course, that was the day the Germans marched into Paris.
Rick.-Not an easy day to forget.
Ilsa.-No.
Rick.-I remember every detail. The Germans wore gray, you wore blue.
Ilsa.-Yes. I put that dress away. When the Germans march out, I'll wear it again.
