It's true that you were in the last occupied row of the balcony at First Congregational Church last night, so perhaps it was reasonable for you to think you wouldn't attract any attention. When I first caught a glimpse of you, I wondered if someone had had a medical emergency requiring mouth-to-mouth resucitation. But no, a few glances in your direction during the Zelenka's many solo passages revealed that you were smooching, early and often.
Perhaps you forgot about the chorus, or thought we'd have our heads so deep in the score that we'd never notice what you were up to. I'm just glad you kept your clothes on and your hands visible.
