I love the contrast that we see in Chapter 16, when Edward comes to visit, between Marianne's "sensibilities", and Elinor's. I love this passage:

"His coldness and reserve mortified her severely: she was vexed and half angry; but resolving to regulate her behaviour to him by the past rather than the present, she avoided every appearance of resentment or displeasure, and treated him as she thought he ought to be treated from the family connection."

Elinor is vexed and angry at Edward's cooling of affection. She has not cooled hers, but here, in public, she is forced to behave rationally and sensibly in the light of Edwards rather blatant indifference to her. In perfect contrast, we have Marianne in the previous chapter, including all and sundry in her laments and disappointments.
