I agree very much with what you have said. I think the more Lizzy interacts with Darcy at Netherfield the bolder she gets in protecting her pride. In Ch. 6 Lizzy confronted Darcy about his listening to her conversations but she keeps it playful asking him what he thought of what she said rather than what are you doing? At Netherfield I think they pretty much clash about topics—what is an accomplished woman, the effect poetry has on love, “yielding to the persuasion of a friend” (10) but (for example) after the “dancing a reel question” Lizzy tells him “You wanted me, I know, to say 'Yes,' that you might have the pleasure of despising my taste” (10) which is “let[ting] him know that I see what he is about” (6) a great deal more directly than she did in Ch. 6. Lizzy gets more personal in Ch. 11. (:D)
