An internal monologue by Jane worth noting, from page 129:
Women are supposed to be very calm generally; but women feel just as men feel; they need exercise for their faculties, and a field for their efforts as much as their brothers do; they suffer from too rigid a restraint, too absolute a stagnation, precisely as men would suffer; and it is narrow-minded in their more privileged fellow-creatures to say that they ought to confine themselves to making puddings and knitting stockings, to playing on the piano and embroidering bags. It is thoughtless to condemn them, or laugh at them, if they seek to do more or learn more than custom has pronounced necessary for their sex.
Jane, at 18, is chafing at her rather secluded life as a governess at a country estate. And, yes, I think I would be too.
