The "Man Code": Fact or Fiction

Is there really a "Man Code"?

This question has become somewhat a topic of conversation since the Mayor of San Francisco violated it by sleeping with a friend's wife. Some journalist argued that men were more upset by this than women because the Mayor had violated this unwritten "Man Code".

I do believe there is a "Man Code" and part of it is your probably should not sleep with your friend's wife except in certain circumstances, e.g. your friend wrecked your Lamborghini. So what is this "Man Code"?

Short is answer is I don't know. And I imagine for each man it is different. It is the rules which we believe in. It is the rules which guides are choices. It is what makes us a man.

I imagine that these rules evolve as grow and mature, but in the end the Man Code is all we are.
