Especially in this passage (it's hilarious that Elinor actually shushes him!!):

She was sitting near the window, and as soon as Sir John perceived her, he left the rest of the party to the ceremony of knocking at the door, and stepping across the turf, obliged her to open the casement to speak to him, though the space was so short between the door and the window, as to make it hardly possible to speak at one without being heard at the other.

"Well," said he, "we have brought you some strangers. How do you like them?"

"Hush! they will hear you."

"Never mind if they do. It is only the Palmers. Charlotte is very pretty, I can tell you. You may see her if you look this way."

As Elinor was certain of seeing her in a couple of minutes, without taking that liberty, she begged to be excused.
