UNBELIEVABLE - the amount of damage you are doing to your children is amazing, you might as well be taking them down to the local bar and leaving them with the local drunks...get rid of him!
Completely on your side but you cannot ignore this or else your kids will see this sort of behavior as acceptable along with the shouting etc and you may end up raising a violant drunk adult and there are enough of them around...
think of your kids!
