"And when you get there, you must tell him at what time you would have him come for you again; and you had better name an early hour. You will not like staying late. You will get very tired when tea is over."
"But you would not wish me to come away before I am tired, papa?"
"Oh! no, my love; but you will soon be tired. There will be a great many people talking at once. You will not like the noise."
"But, my dear sir," cried Mr. Weston, "if Emma comes away early, it will be breaking up the party."
"And no great harm if it does," said Mr. Woodhouse. "The sooner every party breaks up, the better."
"But you do not consider how it may appear to the Coles. Emma's going away directly after tea might be giving offence. They are good-natured people, and think little of their own claims; but still they must feel that any body's hurrying away is no great compliment; and Miss Woodhouse's doing it would be more thought of than any other person's in the room. You would not wish to disappoint and mortify the Coles, I am sure, sir; friendly, good sort of people as ever lived, and who have been your neighbours these ten years."
"No, upon no account in the world. Mr. Weston, I am much obliged to you for reminding me. I should be extremely sorry to be giving them any pain... No, I would not be the means of giving them any pain. My dear Emma, we must consider this. I am sure, rather than run the risk of hurting Mr. and Mrs. Cole, you would stay a little longer than you might wish. You will not regard being tired. You will be perfectly safe, you know, among your friends."(Chapter 25)
I love this exchange in which Mr. Woodhouse instructs Emma in not only what to do but also in what to feel. Mr. Weston makes an equally manipulative, but more subtle, & successful move in raising the possibility of offending the Coles by Emma's early departure & thus buys her more time at the party (that she was loathe to attend in the first place).
