I have been thinking about Mr. Knightley walking in in chapter 1. Mr. Knightley had been absent from the Weston's marriage. Was he not invited to a wedding for someone who had been in the Woodhouse's household for so long? The text does not imply that he went for business. Yet he later pays Mrs. Weston social calls and chats with her as an old friend might. Does this seem usual?

Mr. Woodhouse asks after his daughter and grandchildren, but seems to neglect his son-in-law's health, and only asks about Mr. Knightley's after tending to 'poor Isabella.' This does not seem to be in keeping with his old-world manners. And is Mr. Knightley's visit really that late?
