Answer: W: Frank, I thought you were working in New York.
Q: M: I'm writing to my parents telling them I'll stay here this summer.  W: You're not going home? I thought you were going on a trip to Japan with your family.  M: Well, I intended to go with them, but I thought again and changed my mind.  W: Tell me. I'm interested in knowing what keeps you from joining your beloved family and staying here. It certainly is not studying.  M: No, certainly not. Michael arranged for me to work at his uncle's institution.  W: How much will you be paid?  M: Judy, I don't do it for money, but for experience. Besides, it's voluntary work.  W: You work without payment? That's really something.  M: When will you leave for home?  W: Tomorrow. We'll fly to Hawaii two days after. I really have to pack now.
