In Chapter 20 of Pride and Prejudice, after Lizzy refuses to marry Mr Collins, Mrs Bennet says of her:
There she comes... looking as unconcerned as may be, and caring no more for us than if we were at York, provided she can have her own way.
I know that York is a place in England, but it just seems to be a very strange thing for her to say.
What is meant, in the context of the times, by being at York?
