Cynical, I have often suggested outside activities (and paid for them).
Now it's up to him. He hung up in my ear yesterday, from rehab, when he found out we'd taken the electronics (TV, XBox, computer) out of his room. He can play them downstairs if he follows the house rules. Boy, he didn't like that at all. Tough noogies.
He follows the rules of the house or he can find somewhere else to live. I will love him, support him, take him to meetings and to other places where he can engage in positive activities with positive people, but he will not run the house his way.
