Larry; I don't think think we have to worry about locks on the doors because the physiological place he is in understands his condition, and is keeping him in a safe place, But they are thying to help him to get along with others so they let him write to others with the help of the internet. So we should be nice to him even though he can't spell or write very well he is learning to express himself. It does get bad some days when he forgets to take his Ridlen he will lash out at others because of his condition, and his real bad head aches.
