I am re-reading this wonderful novel, and I was just thinking about the usually gentle and just Anne, and how she seems a little harsh on the subject of her cousins:
"[...] but they were nothing. There was no superiority of manner, accomplishment, or understanding. Lady Dalrymple had acquired the name of "a charming woman," because she had a smile and a civil answer for everybody. Miss Carteret, with still less to say, was so plain and so awkward, that she would never have been tolerated in Camden Place but for her birth." (Chapter 16)
It seems that Anne would expect lady Dalrymple and Miss Carteret to be superiour just because they were "among the nobility of England and Ireland". And, as to Miss Carteret being "plain and awkward", that is hardly her fault. (Other "high society" characters of Austen has been claimed to be awkward, too, if memory serves..).
So - is Anne being too hard on her cousins, or are we to read it just as an example of Sir Walter and Elisabeth`s folly?
