Abraham Lincoln and Prue
"Oh, so now I'm the only bad friend here, then?" He asked this with a smile as well, he was only teasing her. He didn't consider Prue to be a bad friend whatsoever. Sometimes friends didn't keep in contact as much as they would like. Abraham understood that.
Then, after a moment, "How about I take you to dinner, then? To make up for being such a bad friend." Yes, Abraham, that was the only reason you want to take Prue out to dinner.
