“And I certainly _never_ shall give it. I am not to be intimidated into anything so wholly unreasonable. Your Ladyship wants Mr. Darcy to marry your daughter; but would my giving you the wished-for promise make _their_ marriage at all more probable? Supposing him to be attached to me, would _my_ refusing to accept his hand make him wish to bestow it on his cousin? Allow me to say, Lady Catherine, that the arguments with which you have supported this extraordinary application have been as frivolous as the application was ill-judged. You have widely mistaken my character, if you think I can be worked on by such persuasions as these. How far your nephew might approve of your interference in _his_ affairs, I cannot tell; but you have certainly no right to concern yourself in mine. I must beg, therefore, to be importuned no further on the subject.”
