Pride and Prejudice Chapter 37 Summary

Though Darcy and Fitzwilliam are gone, Lady Catherine sends an invitation for Elizabeth and the Collinses to come around, as she is bored and wants company.
Lady Catherine tries to convince Elizabeth to stay at Charlotte's house for a longer visit. When she cannot persuade Elizabeth, she makes a big deal about how Elizabeth needs a servant to accompany her on her trip home.
By now, Elizabeth has re-read Darcy's letter so often that she has it memorized. Her feelings are still muddled; sometimes she feels compassion for him, and other times she's angry with his general attitude.
For her own behavior toward Darcy, though, Elizabeth feels nothing but regret.
As to her family, she thinks it is impossible to ever get them to behave.
Darcy letter did restore Bingley's reputation in her mind, and she feels sad that Jane has been deprived of marital happiness because of her family's foolish behavior.
