Mr. Bennet says in Ch 2 "I honour your circumspection. A fortnight’s acquaintance is certainly very little. One cannot know what a man really is by the end of a fortnight. ..."

There is a hint of truth in this line by Mr. Bennet, even though he meant it in a teasing manner. Is this a little foreshadowing? The neighborhood's opinion of Mr. Darcy is fixed after just a few hours at the assembly.

I think that Miss Bingley is correct in a part of her estimation of Elizabeth's character, "a mixture of pride and impertinence", but this is stated after an acquaintance of longer than a fortnight.

Elizabeth has formed hasty opinions of the Netherfield group at the assembly and then feels certain of her opinions based upon their treatment of herself while Jane is ill. Ch 8 She had very little notice from any but him (Bingley) Then in Ch 9 Elizabeth says that "But people themselves alter so much, that there is something new to be observed in them for ever."
