I mainly avoided talking to them. They were trashy people. They took a beautiful house in a really nice neighborhood that was in great shape 15 years ago and destroyed it. It looks like shit.
It was very upsetting that they were throwing trash in our back yard and on top of our roof that I had to clean up, they were letting their dogs hop the fence into our back yard, their daughter was inviting her friends and using our front yard as it if were her own personal playground (we got after her about that), and they were parking one of their cars over our property line close to our house. I tried to be very nice about it. I talked to a police officer and they said I'd have to officially report it and after so many police calls I could take them to the court and push a lawsuit because it belonged in a civil court. However, I don't own the house, so it'd have to be the owner's decision. Moving was the better option.
