This is not my story but one a good friend told me. Its one of my favorite bad neighbor revenge stories.
I had a good friend in high school/college named Donna. She lived with her family in a very nice house in a rural area where the houses were well spaced apart from one another allowing for plenty of privacy. Next door to her house maybe 30 feet away was a small cottage that had originally been part of the big main property. However it had been sold and turned into a separate property before Donna’s parents bought their house. For many years a quiet elderly couple had lived in the property but when they died their daughter turned it into a rental. The tenants from hell moved in. They were young , they had parties , they had barking dogs they were clueless and oblivious and didn’t really care about their immediate neighbors. Calls to the property owner/renters got them no where. The police issued warnings with no teeth. The noise continued. The worst problems were caused by the dogs , three of them who were left outside in the back yard at all hours of the day and night. If one dog started barking the other two would join in and would keep it up for hours. Donna’s bedroom overlooked the back yard and the dogs frequently made it impossible for her to sleep . She often had to sleep on the floor of the den to get away from the chaos. Donna dabbled in music and had been a singer for several local bands. She had the equipment stored at her house, mic’s speakers, amps all the stuff to make sound really loud. One night after being kept awake by the incessant barking she had had it. She got out two speakers and dragged them to the side yard facing the neighbors house. She quietly got the equipment up and running and carefully rigged two mics to the high wooden fence between the two yards. While she is doing this the dogs were going crazy and barking and making one hell of a racket. Their owners were of course oblivious and sleeping peacefully at the front end of their rental. Donna cranks up the volume and makes the speakers live. The mics picked up the dogs barking and carried it full blast to the cottage and the entire neighborhood. Donna watched while the neighbors lights went on. She was careful to turn off the speakers as the neighbors came into the back yard. But as soon as they left she turned them on again. This went on off and on for an hour til they brought the dogs in. A few nights later the dogs were barking and she turns the speakers on . This time the neighbors went out and yelled at the dogs but didn’t bring them in. Donna cranked up the volume and the neighbors from hell did their best to ignore the noise. A different neighbor called the police and when they came by the dogs were brought in again. This went on for several days until eventually the dogs disappeared. The pot head neighbors never figured out what was going on .
