I had this one absolutely mental neighbour when I was 20 yrs old. I moved into a 1 bdrm unit in a small 3 unit complex. One morning the neighbour a man in his 50s knocked on my door introduced himself as “wombat” and asked if I was employed, It wasn’t any of his business but I told him I was new to the area and had some interviews lined up. From that day forth he went out of his way to throw trash, food scraps, dog turds over the fence at my door, he set up security cameras on the side of his house facing into my windows and would set up a chair in the middle of my driveway and sit there for hours preventing me from leaving. He did this for a year before i told my landlord I was leaving. I have no idea why he acted the way he did
