I really feel for Elinor right there, because she's really working on rationalizing and compartmentalizing her feelings, while attempting to be amiable and pay attention to Edward at the same time. And as well as they know each other, Elinor must have been forced to work very hard to hide her disappointment from him, which can be a very exhausting thing to do. Luckily, it seems that she's had a lot of practise with that. And unfortunately, I have to wait to make a few more points that I'd like to explore right now that I cant! :X
