I was in the lobby of the theater, admiring the effort people put into their attire for the opera, especially the two women in full-on ballgowns. One wore a silver ballgown: she had blonde hair, and she was followed by a brunette similarly dressed up.
I nodded at the brunette and said, "Nice." as if to say, "I approve of the effort you put into your dress." She smirked at me, or winked at me, or somehow acknowledged me.
Imagine my humiliation when I looked on stage mid-opera and saw the silver ballgown, with the blonde still in it, because she was playing Countess Rosina. And then I realized the brunette I spoke to was Susanna, the other female lead.
So, evidently the cast moves through the audience in the lobby beforehand and are not just cute kids playing dress-up who need your encouragement! Who knew? Not me!
I will be looking closely at everyone in the lobby tonight who appears to be well-dressed and might have lung power.
