He's been starting to gravitate more and more to neighbors who use drugs/alcohol. They are not very good people. I have advised him this is not a good idea and I swear he's again being an oppositionall defiant teenager on the issue. HE tells me I cannot pick his friends. He's set up with he VA, he could go to groups there. Nope. He wont' even do his old hobbies. He sits and then wanders over there. I have to keep making up excuses to get him back to our home. I get he may feel lonely. But this is a magor perosnality change on his part. He was always against drugs. He won't follow reason/rational.
