What is the probable relationship between the two speakers?

W: Can we really afford a holiday? We are paying for the house and the car.
M: We are not talking about whether we can have a holiday. We are talking about where and when.
W: Shall we go to Sweden?
M: It’s too cold there. I would rather not go to Sweden.
W: What about China?
M: Yes, but it’s a long way. How long does it take to get there?
W: I don’t know. Maybe we can go to Hawaii.
M: You must be joking. How much will it cost for the two of us?
W: But where do you really want to go?
M: I am thinking of Scotland. Do you know why?
W: Yes, It’s right on our doorstep and so close to our home.
