Mark,
There have been studies about various aspects of this. The problem was probably that as he came out of the lift he felt you were in his "space" - hence the comment.
To give you an idea what level this belongs to, Bruno does the same thing to me! I feed him, but as soon as there's food in his bowl I'm too close, so he growls. :rolleyes:
Much love,
Larry
