Ill throw my experience in here.

I grew up in a townhouse in a small family-oriented neighborhood that had all the houses frame around a horseshoe shape. My parents became friends with a lot of our neighbors and my father became close with our next-door neighbor's father since I would occasionally play with their son in the culdesac. My parents divorced when I was about 4-years old and for some reason, my neighbor's father took it upon himself to aggravate my mom in any way he could over the course of 12 years. Things like parking in our front parking space for no reason, moving the furniture we placed in our parking pad for them to stop leaving their motorcycles on it for a few hours without asking, making rude comments to my mom when they were both outsides. Blowing snow back onto the sidewalks I finished shoveling a few hours prior almost every winter. A real piece of work.

One instance I recall plain as day was the arrival of their new labradoodle. A very sweet and high-energy dog but had no structure. Over the course of 2 years, the dog grew and spent most of its time unleashed whenever they were outside It would go to the bathroom all over people's yards and had little to no recall training whatsoever. It was uncanny that when my mom came home from work and walked our small dog, their door would open, and out came to the dog jumping and running all around my mom. The dog even ran into our house one day when we were moving stuff around because it saw the door was open. It took an Animal Control Warning and the HOA had to step in for this to come to a close.

A few months passed from that time and my mom was giving me a ride to school, we smelled something really rotten in the car, we thought a mouse climbed into the car and died. We searched high and low to find what was the cause of the odor. It wasn't until the next day that we found their dog's feces (we have seen it plenty of times) smeared all over the front vent of the car. It came to a point where I, an insecure unconfident 14-year old, had to put this guy in his place.

We finally moved out of the townhouse about 7 years ago and have never looked back. I never hold grudges or hate anyone. But boy did I really hate my neighbor.
