Summary
Analysis
Darcy and Colonel Fitzwilliam leave the next morning. Lady Catherine, now bored, requests to see Mr. Collins, Charlotte, and Elizabeth again. Lady Catherine supposes that Elizabeth is melancholy for having to leave Rosings herself, but Elizabeth declines the invitation to stay any longer. So Lady Catherine shows her how to pack.
Lady Catherine thinks that because she is so high class she has the right to instruct other people about even the most insignificant things, such as how to pack. Her intrusions on such petty matters make her seem ridiculous.
