Charlotte had hardly time to answer, before they were joined by Kitty, who came to tell the same news, and no sooner had they entered the breakfast-room, where Mrs. Bennet was alone, than she likewise began on the subject, calling on Miss Lucas for her compassion, and entreating her to persuade her friend Lizzy to comply with the wishes of all her family. "pray do, my dear Miss Lucas," she added in a melancholy tone, "for nobody is on my side, nobody takes part with me, I am cruelly used, nobody feels for my poor nerves."

Charlotte's reply was spared by the entrance of Jane and Elizabeth.

"Aye, there she comes," continued Mrs. Bennet, "looking as unconcerned as may be, and caring no more for us than if we were at York, provided she can have her own way. -- But I tell you what, Miss Lizzy, if you take it into your head to go on refusing every offer of marriage in this way, you will never get a husband at all -- and I am sure I do not know who is to maintain you when your father is dead. -- I shall not be able to keep you -- and so I warn you. -- I have done with you from this very day. -- I told you in the library, you know, that I should never speak to you again, and you will find me as good as my word. I have no pleasure in talking to undutiful children, -- Not that I have much pleasure indeed in talking to any body. people who suffer as I do from nervous complaints can have no great inclination for talking. Nobody can tell what I suffer! -- But it is always so. Those who do not complain are never pitied."
