Where does the conversation probably take place?

W: How was your vacation back home in the U. S. ?
M: It was great. All I did was to play and rest and have a ton of fun.
W: Where did you go?
M: We went to the coast to see my cousin for a couple of days.
W: How is she now?
M: Pretty well. And then we flew down to New York City.
W: What did you do in New York City?
M: We were actually outside the city. My grandparents have a vacation home there.
W: You spent most of the time with your grandparents?
M: Yeah. They always miss us.
W: That sounds very good. You certainly look well rested.
