What did Elizabeth accuse Bingley of doing while she herself was doing the same !?

I'm not sure what in particular you mean. Can you give me a chapter? I know she often judges the Bingley sisters as being “superciliousness in their treatment of every body.” Elizabeth is treating them in the same way.

No, I mean only Mr. Bingley ... in general until chapter 26 :)

I think it has something to do with (Bingley and Jane) & (Elizabeth and Darcy).

I think she accused him that he believed Darcy's story about Wickham and he didn't hear Wickham story,while she believed Wickam and she didn't heard the story from Darcy
