One family relationship touched upon in Pride and Prejudice is disappointment in marriage. Mr. Bennet chose his wife for her beauty, with no thought to her working-class relations. He has grown disappointed to find her to be a very silly woman who prattles on about her nerves, gossips incessantly, and says ridiculous things both privately and publicly. His disappointment in his wife has led him to become sarcastic and reserved.
Another family relationship Austen's novel deals with is lack of parental control. Mr. Bennet failed to teach his family principles, and his wife and three younger daughters act poorly because of it. As he should, Mr. Bennet feels that he is to blame for Lydia's elopement with Wickham that endangers his entire family's reputation (Ch. 6, Vol. 3).
