All of Elizabeth's responses to Lady Catherine are as hilarious as they are awesome. The girl is the queen of Deadpan Snarkery:
I was told, that not only your sister was on the point of being most advantageously married, but that you, that Miss Elizabeth Bennet, would, in all likelihood, be soon afterwards united to my nephew, my own nephew, Mr. Darcy. Though I know
it must be a scandalous falsehood; though I would not injure him so much as to suppose the truth of it possible, I instantly resolved on setting off for this place, that I might make my sentiments known to you. Elizabeth:
If you believed it impossible to be true, I wonder you took the trouble of coming so far. What could your ladyship propose by it? Lady Catherine:
At once to insist upon having such a report universally contradicted. Elizabeth:
Your coming to Longbourn, to see me and my family, will be rather a confirmation of it...
Has he, has my nephew, made you an offer of marriage? Elizabeth:
Your ladyship has declared it to be impossible. Lady Catherine:
It ought to be so; it must be so, while he retains the use of his reason. But your
arts and allurements may, in a moment of infatuation, have made him forget what he owes to himself and to all his family. You may have drawn him in. Elizabeth:
If I have, I shall be the last person to confess it.
Do not expect to be noticed by his family or friends, if you wilfully act against the inclinations of all. You will be censured, slighted, and despised, by every one connected with him. Your alliance will be a disgrace; your name will never even be mentioned by any of us. Elizabeth:
These are heavy misfortunes. But the wife of Mr. Darcy must have such extraordinary sources of happiness necessarily attached to her situation, that she could, upon the whole, have no cause to repine.
Lady Catherine: You are to understand, Miss Bennet, that I came here with the determined resolution of carrying my purpose; nor will I be dissuaded from it. I have not been used to submit to any person's whims. I have not been in the habit of brooking disappointment.
Elizabeth: That will make your ladyship's situation at present more pitiable; but it will have no effect on me.
