"There now," Susan said softly. "Take a deep breath and calm down." If she could calm a crowd of five-year-olds, she ought to be able to calm one lost man.
"If I'm right," she went on, "you are even more lost than you think. This is New York, in America, and the year is 1964. Sound like not where you expected to end up?"
Susan tended to slip into her Teacher's Voice when she explained things to people. It irritated her when she caught herself, but it seemed to happen if she wasn't careful. "There's nothing to be done at the moment. People have been popping into the city from all sorts of times and places. It happened to me. And the truly fine problem with things is that we don't seem to be able to leave the greater New York area. It is... most irritating."
A thin smile came to Susan's lips. "And no, I am not crazy, and neither are you." She let her hand move slowly toward that Place where she kept her umbrella, just in case she was going to need to calm this man down.
