But you know the family will never agree to a divorce. I've seen family meetings where the man was physically abusing the wife and they were told to stick it out.
Telling them about their son's shenanigans is just a way to make them aware that they have groomed a devil & you are now stuck with it.
That way, even if things do go sour & you pack & leave... they cant really blame you in the long run.
But as with all things in life, the uncles sit around & try to smooth things over... few weeks later their devil is back to his old tricks again *sigh*
