is not getting to see Mrs. Bennet unable to speak after hearing Lizzy's announcement, and then not getting to hear:

"Good gracious! Lord bless me! only think! dear me! Mr. Darcy! Who would have thought it? And is it really true? Oh, my sweetest Lizzy! how rich and how great you will be! What pin-money, what jewels, what carriages you will have! Jane's is nothing to it -- nothing at all. I am so pleased -- so happy. Such a charming man! -- so handsome! so tall! Oh, my dear Lizzy! pray apologise for my having disliked him so much before. I hope he will overlook it. Dear, dear Lizzy! A house in town! Everything that is charming! Three daughters married! Ten thousand a year! Oh, Lord! What will become of me? I shall go distracted."
