I know she was in London in 2004. But she was in Paris not long ago with New York, then during Toussaint (all saints day break) they went to new york. I don't think schools in Britain have a break for Toussaint, and I can't think of a parallel holiday they might have that would allow her and Andy to break together. So it wouuld seem she's in paris studying or taking a break to live with him or near him, or something. If that makes sense!
It seems like Andrea was going to school in paris too, although he had for some time been studying in montreal (or quebec?)
maybe he enrolled for Wharton or HBS (or some other US business school) for the spring, who knows.or he might be doing a foreign study program affiliated with his school in paris.
