Bah! Dealing with humans. You forget that they, too, are animals. They have instincts, even if they aren't aware. You're much more alert when I am standing, tall, strong, and confident. You are relaxed when I am laying down, with my head low.

You do not actively do these things. Or think about these things. Where humans like you fail is that you do not know how to provoke these reactions from others.
