This such a little gem of a conversation.

"You have not been long enough in Bath," said he, "to enjoy the evening parties of the place."

"Oh! no. The usual character of them has nothing for me. I am no card-player."

"You were not formerly, I know. You did not use to like cards; but time makes many changes."

"I am not yet so much changed," cried Anne, and stopped, fearing she hardly knew what misconstruction. After waiting a few moments he said, and as if it were the result of immediate feeling, "It is a period, indeed! Eight years and a half is a period." (ch. 22)

This takes place the day after the concert, and Frederick is anxious to decipher Anne's feelings, and Anne is anxious to let Frederick know that she still cares for him.

I love the connection made here, the reference to the past, how well they knew each other then, wondering, hoping that time does not change some things. That line of Frederick's - "It is a period!" - and all the longing and lonely years it implies, and that he counts that time in half years so as to be accurate, just gives me goosebumps. So passionate! *sigh*
