I like this from the end of chapter 3:

Whether she thought of him so much, while she drank her warm wine and water, and prepared herself for bed, as to dream of him when there, cannot be ascertained; but I hope it was no more than in a slight slumber, or a morning doze at most; for if it be true, as a celebrated writer has maintained, that no young lady can be justified in falling in love before the gentleman’s love is declared,[*] it must be very improper that a young lady should dream of a gentleman before the gentleman is first known to have dreamt of her.

Someone said in an earlier post that this novel contains a lot more of JA's thoughts and insights, which is what makes it so delightful. She refers to novels and writers a lot, and her comments seem to me to be satirical, at least, in the influence some of these notions had on the readers of those times.
