What are the speakers talking about?

M: You know the party last night? Lots of old faces from college were there.
W: Really?
M: Yeah. Sally was there with her husband: I heard he’ s something very high up and important in some business company.
W: Yes, I heard that too. To tell you the truth, I never really expected her to marry someone successful. She was alway untidy and didn’ t like to work.
M: Obviously, she’ s changed her attitude to life. I mean she was very smartly dressed, and she kept telling me all about how much money their new house had cost.
W: Seriously.
M: Yes, she was really proud of it.
W: Well, she never used to be interested in money at all.
M: By the way, Simon Fox was at the party.
W: Was he? I haven’ t seen him for ages.
M: Naturally, he couldn’ t help asking me questions about you.
W: I think he still thinks that we might get back together one day.
M: Exactly.
W: Well, not much chance of that.
