So I am having some issues with my sister's neighbor. To give you all a little back story, this has been an issue on more than one occasion. Her husband passed away recently, leaving her to live alone, but this man has been an issue before even when he was alive. He would follow her on her morning walks, and would try and talk to her every chance he got. It stopped though.
Everything was fine for a few months up until recently when he came over unannounced one day to talk to her about another neighbor's death. He then proceeded to bring up her late husband causing her to tear up. He then tried to hug her and when she refused he got slightly abrasive. He kept offering her help with the situation but she politely informed him she had plenty of friends and family to help. He got somewhat angry and aggressively asked her why he wasn't a friend and why he couldn't help. She politely told him she appreciated it but that she was fine. He left.
Well the next day she found a letter in her mailbox, from him, noting that she needs to accept help in her suffering etc. Then the other night her doorbell was rung at 3:00AM, she did not get up and answer assuming it was him. She has a fence, and a gate as well as an alarm system. She also sleeps with a pistol next to her bed. The issue is I only live with her for small amounts of time when I'm visiting. This all happens when I'm not there. She is unhappy and I think this guy needs to back off. Every other neighbor is fine and the neighborhood is not bad in the least. What should I do T-Nation?
