In ch.10, when Henry Tilney is comparing marriage and dancing, he says:
"In marriage, the man is supposed to provide for the support of the woman, the woman to make the home agreeable to the man; he is to purvey, and she is to smile. But in dancing, their duties are exactly changed; the agreeableness, the compliance are expected from him, while she furnishes the fan and the lavender water."
I don't quite understand what he means here. What is the woman supposed to do with the fan and the lavender water that is the equivalent of providing support? Fanning him and giving him something pleasant to smell?
