It says something that she has to stop shoveling food into her mouth long enough to answer. And it involves finishing chewing, all while reaching up to swipe the heel of her palm across her mouth. He's actually worried she won't like, isn't he?

She finishes chewing, licks her lips, waiting to see if that's a passable, or if he wants to converse. If everything's good? She's going to dig back in and polish off that plate quicker than anyone would have any right to, short of starving to death.

Beauty and grace right here, Frank.
