I used to live next to my Brother; every time I mowed the grass he would come out and put his '58 Chebby on or over the property lines.
I didn't care, it actually was a Right of Way and I was trying to keep it cut down; he was taking after my Uncle that lived there before him, he used to park an old tractor there. Seems they wanted to tell me it was partly their property... I was just mowing it !
Well as the story does, I got some grass on his new wheels, I did ask him to move the truck so I could mow but he didn't, I tried to stay far enough away and blow the grass in the opposite direction but some got on his wheels. I didn't think to much about it, I left for a while and when I came back he was all over me... I got grass on his wheels... !
I think if he wasn't my brother he would have taken it further... he then broke out in a long story of how I got more things than he did, how I am ahead of the curve on financials because I got more... GIVE ME A BREAK, all because of grass on the wheels, Worked for what I have.
I left the Right of Way alone after that, the grass grew about two feet high and stayed there and a small tree happened...LoL, I got tired of his BS and trying to KISS HIS A** to keep the peace, I moved 3000 miles away and haven't heard a word from him since... that's almost six years ago now, life is good, and no one to bothers me anymore.
As you can see things can escalate so fast, things happen, he even came at me and I just held him off but if he had swung at me, who knows where it would have gone.
Added: My neighbors now... eye shot the closest is about 1/2 mile most are 3/4 to a mile, we don't bother each other unless we are in a bind and we all respond as needed. Three of them are a little higher up than me at 2000 feet but I have a good view of their houses and we do watch each other property, we even send lists around about vehicles that should be in the area and if we are going off, and if there will be additional vehicles coming for whatever purpose. The arrangement works well; I saw a vehicle in one guys yard and called him at work...cell phone, he called his wife and then called me, it was friendly, so all went well and the system worked. This is how neighbors work together to get things done and help each out.
