Thanks all. I talked with him and told him I knew what happened. I told him if it happened again that he could live with me. One argument that we keep having is whether he is allowed to drink or not. He is 22 so he feels he should be able to. I feel that since he has a problem with alcoholism that he can not drink and live with me. I'm not sure if i am over-managing him too much. Anyways. our discussion went fairly well.
