By the time she trails off he's smiling, and he can't help it, and he's not mocking her, not at all, he's smiling because, well - "You just called me your boyfriend."

He has to point it out, he does, even if she might be about to storm off. It's alright, because she said it and he hadn't even asked for it, he's not even sure of the word boyfriend. It's so very modern, and he's never had the occasion of applying it to himself before.
