Well, I find some of Lydia's remarks worthy of note.

(about a previous reader of the book): She has a most observing thumb; and, I believe, cherishes her nails for the convenience of making marginal notes.
I have the same habit, alas, and feel pretty uncomfortable under Lydia's censure. :)

(about Beverley): I intended only to have teased him three days and a half, and now I’ve lost him for ever.
The precision of it!
