At the beginning of ch.15, I was struck by this:

After laying out for some compliments of being deeply regretted in their old neighbourhood, which Anne could not pay, [Sir Walter and Elizabeth] had only a few faint enquiries to make.

So the two of them are fishing for compliments about how much people miss them back home (except that apparently nobody does)! I can just hear the conversation...

Then, later in the chapter, Sir Walter comments:

"If I thought it would not tempt [Mary] to go out in sharp winds, and grow coarse, I would send her a new hat and pelisse."

Anne was considering whether she should venture to suggest that a gown, or a cap, would not be liable to any such misuse, when a knock at the door suspended every thing.

So, Anne is not the only daughter who can be economized on...
