Spirit shows who's boss.

This should not be funny but some how it is. We have had Spirit home just 3 days and some friends came over. I was working on wrapping his perch/basket handle with sisal for footing and Spirit was on the back of the couch. This guy comes in saying ALL animals love him and wants to hold Spirit. I tell him this is not a good idea we really do not know how he is with people yet. At this Spirit runs across the back of the couch and flaps over to the guy. He sits there all smug as Spirit walks up his cheat and leans in for a kiss. Well at that point Spirit grabs the guys upper lip and twists hard! I do have to say for the guy he did not yell out or try to hurt Spirit at all. I ran over and pick Spirit up and put him in his cage. Spirit sits there and looks at the guy with the now bleeding lip and giggles really evil! For now on it seems Spirit has to be on me or in his cage when folks come over until we know him better.
