"I'm from the North. We rarely have books, let alone people who can read or know their letters. So you may have to explain what you do to me. Assume I'm a dumb, eh... barbarian, you could say."

He flashes a smile, letting Aya in on the secret that maybe he's not as dumb as he pretends, but he certainly isn't familiar with modern society.
