Read it through once

It had been settled in the evening, between the aunt and niece, that such a striking civility as Miss Darcy’s, in coming to them on the very day of her arrival at Pemberley--for she had reached it only to a late breakfast--ought to be imitated, though it could not be equalled, by some exertion of politeness on their side; and, consequently, that it would be highly expedient to wait on her at Pemberley the following morning. They were, therefore, to go. Elizabeth was pleased; though when she asked herself the reason, she had very little to say in reply.
