What is the relationship between the two speakers?

M: Hello?
W: Dad, it's me, Kirsty.
M: Kirsty! How are you?
W: I'm fine, but still a little tired.
M: I can imagine. What's the work like?
W: It's still too early to say. But I think it's going to be really good. It's a big company and everybody's been so kind and helpful.
M: And how about the city? Have you seen much of it yet?
W: I've seen a bit. It just seems such a big, busy city. I don't see how I'll ever find my way around.
M: I know. Big cities can seem really strange and frightening at fast.
Where are you living?
W: Well, I find a tiny apartment. It's in the downtown area and it's close to work.
M: It all sounds really interesting. Hope you'll enjoy yourself there.
