(((Chic))) I ache for you, knowing how frustrating it is to have a child still living at home who doesn't help themselves.
I second sending the slapomatic to use on him since he doesn't listen to reason.
I am so sorry you have to live like this due to his problems. I wish I could wave a wand and make him move out.
I think he knows he is spouting bs.
So sorry you have to live with this.
