Like most have said: take the high road. You don't want the toothless hillbilly knocking on your door, under the influence of something, pissed off because you made a fuss directly towards him. It doesn't end well. I've been there with a cocaine addicted neighbour I had back in the day that would come to my door and ask my roommate for money/take her kid at all hours of the night.
That .... stopped quick, but I wish I went about it differently, because it was ....ing excruciating.
