What is the relationship between the man and the woman?

W: Where are famous Americans from?
M: They’re from all over America. Some of them weren’t even born in America, but came to America and became U. S. citizens.
W: Do you happen to know where Benjamin Franklin was from?
M: Boston. Benjamin Franklin was a printer, writer, philosopher, scientist, and diplomat! Is there anything else you’d like to know?
W: Yes. I would be very grateful if you could show me where to find the books about famous Americans.
M: Sure. If you follow me, I’ll show you how our library is organised. Everything that we have in our library you can find is listed in our computer system.
W: Really? How does it work? How can I find the books I’m looking for?
M: Just type in the name of the author or the title of the book and the computer will tell you where the book is located in the library. It will also give you a short description of the book.
W: How convenient!
