She's absolutely hopeless at detail. I read a short story of hers, years ago now, which was set in London, and one of the main points of the story was that the hero (allegedly British) couldn't afford dental treatment for his 9-year-old daughter. Put me right off most of her stories (except "Even the Queen", which really makes me laugh every time I read it).

To be fair, she is American and in America, certainly in the 1990s, one did not address University staff by their first names. Also doctors and professors are the other way round. I don't know if you've come across the excellent "Separated by a Common Language" blog, but this post, from some years ago, is quite helpful on the distinctions between forms of address here and there.
