“Roberta didn’t acknowledge my presence in any way and I got to thinking maybe she didn’t know I was there. I began to pace myself in the line, jostling people one minute and lagging behind the next, so Roberta and I could reach the end of our respective lines at the same time and there would be a moment in our tum when we would face each other”.
