Even though she was smiling, Greg winced a bit and let go of her hand instantly. "Yeah, sorry. I don't mean to be. Not at all the time, anyway."
He buried his hands in his pockets to keep from using them. He felt awkward enough without accidently grabbing or touching or shaking her hand too hard again.
His smile returned, hesitant, when she started in about the house elves. "I dunno if I'd call them sweet, really. I mean, it's almost like they've got to make sure we have everything we need, and that's a bit odd, isn't it? I mean, they need to do it like people need to eat or sleep or something." Bloody hell, he was turning red again. He shouldn't be allowed out around people. "Anyway, they're funny. And I..."
Hold on. She just asked him to get food with her.
He stilled, thinking about her words. No, yeah, she definitely asked if he wanted to get something to eat with him. Was that...did that mean anything? Probably not, but...but it meant she wanted to get some food. With him.
He wanted to duck out of that corridor and run and find Draco and ask him what the bloody hell people were supposed to do when things like that happened. But instead he nodded, unsteady. "Yeah, okay."
