It seems that JA was a country girl at heart and so made her heroines also, none of which express a preference for town over the country and none actually even want to go to London for the sake of being in town—Marianne only wants to go to town to see Willoughby. Eleanor and Marianne who do go to London have a miserable time and then have problems actually getting home because they must rely on the kindness of friends to eventually see they get there. The individuals, who express a preference for or seem to be fond of town, also seem to exhibit this dissipation and vice of which JA speaks so is it a coincidence that they are also either villains or fools in the stories?
