B. Who comes and goes to his house.
C. calling the cops on his teenage daughter when he is not there
He has,
A. Cursed me out in the middle of the street while I am taking the trash to the curb.
B. Come to my door and offered to have his sister come and take care of my wife
C. Come to the door and acused my wife and I of all of the above.
We live in close enough proximity that a restraining order I doubt would be much good (about 15 yds from the prop line to his front door). What the fuck can I do, it's almost imposible not to run into him. That said I shouldn't have to deal with that shit just because I am in front of my own house.
Today he cursed me out for calling the cops on his kids, last night the cops did come. I didn't call them, the lady down the street did, on my kids too. One or more of the kids in the neighborhood got in her flower beds or somethings so she called the cops on all of them, my kids as well. I should have known when the cop came to my door that I would have to hear about it the next day...
He even called the secret service 
on speed dial to prove it...
