The moral of the story is : if you have to commit adultery, do it secretly, don't get caught. Just as the crime is not looting the country ( in which case most of our politicians would go to jail ) but being caught looting it ( in which case also there is great doubt that they will ever go to jail ), so also the offence for which a wife will be deprived of alimony is not committing adultery but being caught committing adultery. So just be a bit discrete.
