Of course he agreed immediately when she suggested they walk; he still would have followed her anywhere. It was a good thing, probably, that she didn't reciprocate his crush, and that she wasn't the sort of girl (he didn't imagine) to suggest slipping away from the party to do something scandalous.

So if you can start writing back and forth with her, I think that'll help you get what you want sooner."
