Are you psycho?

So what do you do when someone you loves becomes obssesive about something? Let me give you a little back story.

My mother (God love her) lives in an HOA community. They are not 100% full so there is a property management company making all of the decisions for the HOA along side the builders. My mother being the helpful person she is has really got involved with the community. Planning parties, walks, charities etc, but she also seems to get involved in any and ALL drama. My mother never does anything half way so when she's involved she will no every story, every detail, who said what and why they said it. She likes to believe she is not a gossip, but the women talks to everyone who will listen. I love her please don't get that wrong, but how do I tell her she goes over board? She is to the point in her community that many of the neighbors want nothing to do with her. I will admit some of those people don't want to have to deal with her because she has no problem enforcing the rules, but the other people just don't like her because she is drama.

Now things are getting bad. Her neighbor built a HUGE fireplace and put in a ton of landscaping so much landscaping that his house looks a little ridiculous. He just keeps adding and adding. The problem is that he has not got permission like he is required to from the HOA or the county commisioners and zoning boards. He put this huge fireplace only 3 feet from his fences and tress which is against county ordinance. They have come out and told him it was not right there has been a hearing and he was told he had to take it down. He won't do any of it. Well being the fact that he lives across from my parents house my mother feels she needs to get involved. Her reason was his craziness was bringing down everyone elses property value. Now shes is obssesed with "taking him down" Its freaks me out. She takes pictures of his house, eves drops on his conversations and is getting the housing community involved. Granted he is not a good person, but I'm affraid if she pushes this to much more he is going to do something bad. She has already over heard him saying he was going to have her taken care of. I'm not sure what that means, but it scary. All the while I'm sitting here wishing she would just drop it a little bit. Don't get so involved. It went from being something that was good for the neighbor hood to being something very personal to her. She talks about it all the time and I wonder what makes her this way? Am I going to be like this too? Will I then pass this on to my daughter.
