I don't get it INH... is this guy a marine? Or on your course? I think I just thought that because you knew the guys he was living with... surely there is some support network in place...? I met a homeless guy walking the dog some months back who was an alcoholic and had been kicked out of a sober living house and I was able to find him a place to go where someone could help him. I agree that getting involved as an individual may not be the best idea but there must be some community program somewhere for him to go...
