 We ride the ears because when you ride the ears, you're riding his attention. The open face of the ear points to where the eye is looking. Now, I could wiggle my inside leg to say to him, can you look to the right? See, right ear back. I could wiggle my left leg and I could say, could we get you to look to the left? It'd be no different than if somebody walked up from behind you and they tapped on your right shoulder and you said, huh, oh, hi.
