Allison, my parents, my sister and I went to a flute and piano recital last night. It was in a large auditorium at Allison's university.
Before the starting time, I announced I was going to the bathroom, and my dear wife pointed to where she thought the bathrooms were, following a passageway on the side of the auditorium, which I followed, with my father who also decided to go to the bathroom.
The end of the hallway led to a men's bathroom, but the door was locked. It looked like someone was inside, so we sat down and chatted. A few minutes later, the musician who was going to be playing the flute that night, a visiting musician, came out of the bathroom, and we realized that we were in the private area for performers. (it didn't prevent us from using the bathroom, which we did to great flute practice background ambiance).
