You could try to get a restraining order? I'm not really sure. Or the next time she wants to spy through your bushes, go spray her down with your garden hose ("oops! I was watering the bushes and didn't see you there!").
Maybe she's jealous of you? Maybe she's just a miserable old hag. I would just tell her "mind your own business and stop being a nosy old hag". Then I would dress in some short shorts, a skimpy top, and I'd go mow my lawn. Then she'll really have something to talk about ????
I had the same problem with privacy and comments from my neighbor. I had a privacy fence installed with the beauty side of the fence facing me. It was on the property line between the two houses but still on by property so my nosey neighbors could not hang,paint.or anything to the fence. Solved my problem once and for all.
Sadly it's called freedom of speech. You cant do much about her talking to you really. If she's on your property then you can tell her she's not allowed there and get her for trespassing if she does it again.
Aside from that tell her how you feel and not Tao talk to you if you must. Just because your neighbors doesn't mean you have to be friends.
Invest in an air horn. If she spies on you creep up to the fence and give her a blast. With luck she will have a coronary.
You could get a digital camera and record her doing these things. Then report her to the authorities with video evidence.
Carry around one of those small search and rescue horns. As soon as she opens her mouth in your direction, let loose a blast.
I would laugh at every comment. Uproariously. A**H***s hate laughter.
They moved in next door about a year ago and since then the mother has had a vendetta against me. She has started commenting on everything I do, everything I wear, I get no privacy at all. Her kids have picked up on it and started doing it now. I have caught her spying on me through the bushes over my fence. There is much more she has done. It has all started to get me down lately, I dread going in my garden for fear of hearing what else she has to say about me. Why would somebody behave this way toward a neighbour?
Anyway, what can I do about all this? What are my legal rights?
