The older I get, the more I like Lady Catherine. This is partly because, as an ageing woman, I have more sympathy for other older women. Older women are often mocked in fiction: dismissed as silly, no longer beautiful, and frequently poor. Even Jane Austen was not beyond ridiculing them – think of Miss Bates and of Lady Bertram – but Austen also treated many with respect, even when her characters do not (Marianne Dashwood is extremely rude to Mrs. Jenkinson, and Emma is impatient with Miss Bates).
Lady Catherine may be proud, but that is something to be expected of a woman who is the daughter of an earl and the mistress of Rosings Park. And she has, in my opinion, many admirable character traits.
