OP, I don't know what to say really. Wandering for 40 years, this guy is completely unstable!!! No one wonders for 40 years without being unstable.

Also, missing all teeth, MANY times that is a meth problem!!!

PS, drug addicts will NEVER tell you're they're doing. They will always tell you they QUIT or have never done the stuff before. Trust me, I know, unfortunately, had people close to me that were users, they were always "quitting".

You could have helped him WITHOUT bringing him to your home!!!!

Stay safe OP!!!!!
