I believe that snakes are base creatures and everything falls into something to eat, something that is a threat, or procreation. I don't believe my snakes believe they can eat me, nor do they think of procreation either (I hope ) When I first bring a new one home it is likely they see me as a predator that will eat them. This is the interesting part that somewhere along they way they over come the fear that I will eat them. That I want to say trust for lack od a better term, is what is being discussed here. There is a point where my snakes no longer see me as a threat but as something else. I wish I had a word for what that is but I don't really.
