RE: Neighbor Problems...
I would ask him politely one more time, then I would get the law involved. Just tell him you think he's a good guy and you have a slight misunderstanding. Tell him your concerns, and listen to his. I always try to reason with people before I get the "law" involved.
Ifhe fails to cooperate I would then take things to the next level. I would call the police and tell them there isa minorin possession of a firearm and heis currently discharging it nearyour residence.
