Shy?
I guess whoever wrote that thang said being satiated is shy.
I have it on good authority from an old friend and biology major that when big snakes are hungry their prey cannot get out of the way fast enough, and that includes humans. Apparently they can fling themselves on their prey quicker than you can blink your eye. And then... he showed me his snake lecture and vids.
So much for the slow moving, shy theory.
