The word "home" should be a synonym for peace and quiet. It should be a safe space to hide from the world once the week is over, and happily enjoy your own company. It should also be a place to invite friends and family over for a cheerful afternoon of laughs and good company. A house can be plenty of things, but it shouldn't be a battlefield.
Coexisting with other human beings can be hard, especially when they live right next door. Try fitting into this person's shoes: you like your space to be clean and organised and appreciate hosting small get-togethers. However, you cannot fully rely on your friendly company, because your neighbour insists on placing giant things in your shared backyard, making it very challenging for your guests to actually get to your front door. Also, he likes to stay outside doing things you feel are a little embarrassing, to say the least.
It's important to mention that the whole "wind chimes" debacle was not the first step in this escalating situation. The owner of the story tried to reason with her neighbour and, when that failed, even tried to get the actual owner of both properties involved. Not even a timely warning could keep her neighbour from filling up the backyard with junk. That's when she decided to fight fire with…wind chimes. A lot of them too. So much so that other neighbours are starting to be annoyed by the situation, for the sound of the wind chimes becomes unbearable with every passing day. "The chimes come down the second he stops hanging out outside my window and clears the junk," was her answer, after everyone requested her to put them down.
We get it. The messy neighbour is definitely being very inconsiderate by putting his things everywhere, not taking into account that the backyard in question is shared by two renters. However, she is also being inconsiderate. Her actions have involved every other neighbour on the property and continue to escalate a situation that, at this point, needs the involvement of proper law enforcement officers. We will give it to her, though; she is very creative. Everyone here should be using that exact same creativity to try and figure out a solution that benefits all parties. What side of the yard would you be on?
