In the first act, Susan and Harry prepare lunch for Harry's daughter Michelle and her friends. Susan: Michelle and her friends are at the aquarium in Brooklyn. They come back here for lunch, then go uptown to the Museum of National History. Susan likes living in New York city. Susan: It's so convenient. I can take the bus to work ... or the subway ... or a taxi. Harry lives in the suburbs, but he likes the city too. Harry: The truth is, I'd like to live in the city. A little later, Harry and Susan talk privately as they wait for the girls to arrive. Harry: They'll be here any minute. Susan, I'd like to continue this conversation later. What do you suppose they are talking about?
