"No -- why should he? If it were not allowable for him to gain my affections because I had no money, what occasion could there be for making love to a girl whom he did not care about, and who was equally poor?"

"But there seems indelicacy in directing his attentions towards her so soon after this event."

"A man in distressed circumstances has not time for all those elegant decorums which other people may observe. If she does not object to it, why should we?"

"Her not objecting, does not justify him. It only shews her being deficient in something herself -- sense or feeling."

"Well," cried Elizabeth, "have it as you choose. He shall be mercenary, and she shall be foolish."

"No, Lizzy, that is what I do not choose. I should be sorry, you know, to think ill of a young man who has lived so long in Derbyshire." (Chapter 27)

It is interesting that Lizzy realizes this about herself just now. It is, I think because she recently reevaluated her feelings, motives, reasoning towards Wickham and Darcy and found them wanting. Now she is more aware of how her pride and prejudices can lead her to make mistakes and is struck again at her previous position—it probably is shocking to find she had similar thoughts with Lydia who she has classed as her very foolish and silly younger sister. I do not think Lizzy actually has much similar to Lydia in the brain department because Lydia is speaking of Wickham whom Lizzy was prejudiced to excuse and gentle all his deficiencies because she liked him. I too think Lizzy is harking back to when she could not quite agree to see Aunt Gardiner’s point about Miss King and Wickham in Chapter 27. I think Lizzy has learned a lot about herself recently and this sudden epiphany must help her to look at herself as others might see her. ;D
