Many decades ago, I was attending a Vladamir Horowitz concert. Of course, it was a sell-out with stage seating. Entering the building a young woman threw up on an impeccably dressed man. She apologized. He was speechless. I had a stage seat. Guess who was sitting next to me? During the first piece, she took her purse, dropped its entire contents onto her lap and then threw up into her purse. As Horowitz left the stage, he was surprised to see the young woman exiting with him. Fortunately, she did not return.
