So good to read this thread. We are dealing with this exact situation (again and again) right now. Just yesterday I gave Peter Pan the word: finishing off the milk and juice for your post-midnight snack and leaving all the dirty plates around is a DEAL BREAKER. The deal being that in my house, whatever other issues he has, he must show respect for us and for the household. So today I have to follow through. He may or may not have another place to go tonight, but I actually feel I must toss him out for having drunk all the OJ and left a melted-cheese-covered plate on the kitchen table. Feels like such a minor infraction, but I agree--the dysfunction, the inability to see other people as people and not as servants or robots, is major. And meanwhile my energy is so very low because of dealing with him that I dread the explosion that will come when he learns I mean business. A lot of the difficulty, I think, has simply to do with energy. That's why we rely on caffeine!
