To repeat myself (for the third time): the children wouldn't suffer if their father had seen fit to keep his genitalia to himself. Once he has done otherwise, thanks to old man Murphy's law, sooner or later the matter will get around to his children. It makes no difference if it is tabloids, "candid friends" or surprise discoveries in old drawers; the pain is the same. And anyone who thinks they can do the one and not cause the other is also guilty of wishful thinking - a fool as well as a knave; and stupidity is the one sin that God punishes, and punishes always, right here on earth.
