He raised both of his eyebrows now in curiosity. For a moment she was again being much to pessimistic, though this only served to fuel his need to show her the light, get her to understand. But so suddenly she seemed to have a different take. That was good for her, because he could have gone on forever about her generalization of how men and women love.
If he was already grinning, it grew wider.
"Yes!" He exclaimed. "That's perfect, that's how the narrator felt! True love like that just can't fade! It will get stronger!" He straightened himself up a bit slightly embarrassed that he was shouting, not yelling though, he was only excited.
He didn't necessarily agree with her that the author was drawing from personal experience, only because he had never had such a romance, but he indeed had strong feelings on the matter. In any case, he decided not to argue that point, at least not yet.
He scratched the back of his head quick to make up for his little scene. "Why were you so quick to change your mind?" He actually wanted to ask her many questions. He was quite curious to know about her own love life cause this had to be the reason she was so critical, or not.. maybe it was her parents influence, or all the books she had read. He just wondered how she became so guarded about the matter.
