When I lived in KS my roommate and I had the upstairs neighbour from hell in our duplex. The first night while we moved in she had him doing a million and one different favours for her, like changing lightbulbs, getting stuff down from the attic etc. She'd leave her dog on a 30ft tie out in the shared backyard for hours on end, right in the middle in front of our door, making it difficult for me to take mine out on a leash and not get leapt upon. He would bark and bark at us through the window in our own place. I put our dogs' stakes way at the back of the yard, because if I put them nearby she'd promptly put her dog out too and we'd end up with a huge tangle. Then she was aggravated because we used a chain instead of a covered cable for the dogs, and I would let the dog outside only to find the chain in a heap on the path and not attached to the stake. It was easier for me to take my dogs to a patch of grass across the street, so I took to doing that, and came home one day to find a miniature picket fence erected in the yard with signs declaring a 'No poop zone'. The weird thing was that it surrounded the area that her dog had access to. If I put a bowl of water out for the dogs, i'd find it emptied and sat out of their reach where she had tipped it out because 'it might kill the grass underneath.' Sorry lady, but my dogs' thirst comes before protecting 5" of grass. Her grandson liked to play with my dogs, which was fine, but he would knock on the door four or five times a day wanting to come in and see them. We'd have to hide and pretend we were out LOL
Since she was upstairs, her tornado shelter was our apartment and she was allowed access in an emergency. She even had a key to our place. She would show up nightly during tornado season unannounced, when there was just an advisory, complete with her unleashed dog, cat, and grandson and right in the middle of our supper time. She'd leave notes on my roommate's vehicle complaining that he had parked too close to the garage door and she had to walk around the car to get to hers instead of between the hood and the door.
We finally had enough of her grump, and called our landlord. He said that she had been the same way with the last tenants, complaining to him about what time they got home at night and other petty things. He believed she was doing it because there had not been downstairs tenants for a while, and she liked having the place to herself. He called her to tell her to straighten up, and it went from bad to worse. We'd get home to piles of dog poop on our steps and patio, and she would be as noisy as she could when she was home. We ended up calling the police on her because we were concerned that the loopy woman had keys to our place and might poison the dogs or damage our property. She would act like she wasn't home when they called on her, then crash around incessantly as soon as they were gone. It got so silly that we would call them out two or three times a night just to get some peace. Finally she decided to move, and we had a party the day she left...after she'd moved the van blocking our driveway LOL
