[Armin's voice dips with sympathy.] Animals are a lot more open about mistrustful toward what they don't understand. They don't have a bunch of social rituals to prove to each other they're not aggressive - or um, rather, they're not the same ones.

Speaking of that, I'm Armin. I'm new to this place.
