One of the things I love about Austen is how she takes unapologetic pleasure in people's foibles and the less than perfect feelings which make us human. For instance here, how she laughs at Walter Elliot; "...the Sir Walter Elliot, who united these gifts, was the constant object of his warmest respect and devotion." And in Pride and Prejudice there is a wonderful phrase about Miss Bingley's and Mrs. Hurst's behavior restoring to Elizabeth "all the pleasure of her original dislike". I get the sense Austen thinks we would all have a lot less fun in life if we were all perfectly kind, selfless and forbearing at all times, and that she loves people more for being human than being perfect. In fact I recall from one of her letters to her niece Fanny, her delighting in Fanny's inconsistencies and caprices.
