I don't want to go into Austenuations territory, but on this re-read of "Persuasion", I was reminded of P&P a few times. In that novel, we are told that Mr. Bennet has managed to keep his wife's spending just within the limits of their income, while in "Persuasion" it was Lady Elliot (while she lived) who did the same for her husband.

Uppercross is three miles from Kellynch, as Netherfield Park is three miles from Longbourn. I wonder if Anne ever attempted to walk that distance?
