He does now. It took us way, WAY too long to figure him out. Let's say his behavior did not endear him to my girlfriend, and he was a little leary of her.
Now that we understand him, their relationship has improved 1000%, and he is the most affectionate of my brood. He does play aggressively with the others, and when he accidentally hurts us (thru play excitement) we now shrug it off, because he can't hear us cry out.
