"I can guess the subject of your reverie."

"I should imagine not." (Chapter 6)

In Chapter 6 Darcy tells Caroline that Lizzy is a pretty woman with fine eyes. I imagine the friends to whom Darcy disparaged Lizzy’s appearance were Bingley at the assembly ball and later the entire Netherfield party. His response to Caroline of "I should imagine not." implies he has told Caroline in the past something of the opposite of what he is now thinking. Here at last is my point, if Darcy regretted disparaging Lizzy’s appearance within her hearing or to his friends then should he not say something along the lines of he had been wrong? Yet he does not do so—it seems to me Darcy expects Caroline to accept his change of opinion without question. She does of course with astonishment. I think Darcy’s failure to acknowledge his change of opinion to Caroline is a good indication that Darcy, at this point in the novel, does not regret his behavior at the assembly. ;D
