Read the following passage from Jane Austen’s Pride and Prejudice:
Mr. Bennet was among the earliest of those who waited on Mr. Bingley. He had always intended to visit him, though to the last always assuring his wife that he should not go; and till the evening after the visit was paid she had no knowledge of it. It was then disclosed in the following manner. Observing his second daughter employed in trimming a hat, he suddenly addressed her with:
"I hope Mr. Bingley will like it, Lizzy."
"We are not in a way to know what Mr. Bingley likes," said her mother resentfully, "since we are not to visit."
"But you forget, mamma," said Elizabeth, "that we shall meet him at the assemblies, and that Mrs. Long has promised to introduce him."
"I do not believe Mrs. Long will do any such thing. She has two nieces of her own. She is a selfish, hypocritical woman, and I have no opinion of her."
"No more have I," said Mr. Bennet, "and I am glad to find that you do not depend on her serving you."
Mrs. Bennet deigned not to make any reply, but, unable to contain herself, began scolding one of her daughters.
"What is your principal object in coming?" said Elizabeth to Mr. Darcy, who was to be engaged in conversation with her.
"Your conjecture is totally wrong, I assure you. My principal object is to see you and to judge, if I can, whether I might ever be capable of loving you."
