i am so upsert right now I can't stop shaking .......I am seriously thinking about going and talking to the Police . This IS harrassment and it IS affecting my well being
I believe you should call the police. He's harassing you and stalking you. If nothing else, a conversation with the police will upset/annoy the elder. There's no reason why you should be the only one who is upset. Let him have a little inconvenience too. It might put a little damper on his gloating, which he's undoubtably doing right now.
Sometimes, when someone is an asshole the best way to deal with it is by being a bigger one. I know it doesn't come natural to everyone, but unfortunately that's the only language some people understand.
