"You know, so do you," I say, bumping her shoulder back in turn. There's a moment where I wonder if I should lean over and kiss her, just like a peck on the cheek or something. But I'm not sure if that's overkill or underkill or what, and there's the previously discussed situation where I don't know myself well enough to know if that's a place where I should be going. So I go with something safer and say, "We should do this again."
