Molly and Arthur in different houses at Hogwarts?

Another discovery whilst reading GoF to my daughter the other night.

Just prior to the third task Molly and Bill turn up to spend the day 
with Harry as his surrogate family.  Bill says he hasn't seen 
Hogwarts for five years and asks about Sir Cadogan and the Fat Lady.

Molly says about the fat lady:

"She was here in my time...she gave me such a telling off one night 
when I got back to the dormitory at four in the morning-"

"What were you doing out of your dormitory at four in the morining?" 
said Bill, surveying Mrs Weasley with amazement.

Mrs Weasley grinned, her eyes twinkling.

"Your father and I had been for a night-time stroll," she said "He 
got caught by Apollyon Pringle - he was the caretaker in those days -
your father's still got the marks."

It doesn't seem like Molly and Arthur were returning to the same 
dormitory.  Molly returned to the dormitory where the Fat Lady was 
stationed so you'd guess it was Gryffindor but I suppose its not 
definate.

I wonder what house dormitory Arthur was returning to and why they 
really were meeting at 4am!
