We have a well defined set of behaviours that are acceptable to us which we modify rarely. Fairly broad and fairly all encompassing, we augment them with openness and honesty.
We break what sociaty may see as rules
I say we write our own rules
Every thing we do is by mutual consent, so no hard and fast rule required, we discus things, come to a decision and act on it
How many of society's (as opposed to the Law's) rules are totally absolute? The vast majority have a handy little addendum at the end that starts "unless - - - ".
I suppose the majority of the rest are to do with protecting the vulnerable.
