So you're saying that, by default, if a snake is not stressed, its automatically happy with the status quo?
Very interesting observation and not one that I share in the least. But to each his/her own.
P.S. Snakes don't have moods or emotions. Human qualities and one of many put on reptiles for reasons unknown to me. You'd probably be surprised at what a snake is built to do in a normal day and what, if given the choice, a snake (particularily a BP) would choose to do.
