This is the scene where Mr Darcy makes his most unwelcome proposal to Elizabeth Bennet. She is making it very clear that she is less than impressed with his offer.Elizabeth answers:
"In such cases as this, it is, I believe, the established mode to express a sense of obligation for the sentiments avowed, however unequally they may be returned. It is natural that obligation should be felt, and if I could feel gratitude, I would now thank you. But I cannot -- I have never desired your good opinion, and you have certainly bestowed it most unwillingly. I am sorry to have occasioned pain to any one. It has been most unconsciously done, however, and I hope will be of short duration. The feelings which, you tell me, have long prevented the acknowledgment of your regard, can have little difficulty in overcoming it after this explanation."
Mr. Darcy, who was leaning against the mantlepiece with his eyes fixed on her face, seemed to catch her words with no less resentment than surprise. His complexion became pale with anger, and the disturbance of his mind was visible in every feature. He was struggling for the appearance of composure, and would not open his lips till he believed himself to have attained it. The pause was to Elizabeth's feelings dreadful. At length, in a voice of forced calmness, he said --
"And this is all the reply which I am to have the honour of expecting! I might, perhaps, wish to be informed why, with so little endeavour at civility, I am thus rejected. But it is of small importance."
Oh, go on, don't stop there, read that chapter again or better still, the whole book!
