We all have families that embarrass us to some extent, but the Bennet family takes it to a whole new level, creating endless problems for the two eldest Bennet daughters. Like them, love them, or hate them, though, you can't escape family in Pride and Prejudice. Worse, your family's behavior reflects upon you. If your sister runs off with a scoundrel, society will hold you in less esteem. Conversely, if your sister marries well, society will hold you in better esteem. Family in Pride and Prejudice, therefore, affects your opportunities and life chances in a very real way.
Mr. and Mrs. Bennet are bad parents, but they do love their children.
In the novel, young people are shown to be "raised" by friends much more than by their parents.
