Thanks for your thoughts.
That's the reason I'm in this mess, because I was that kid too, and I didn't want to be that neighbor. When I first moved here, I smiled and waved at everyone. I brought them fruit from the farmer's market and pies from the bakery. I was the "nice" one. I let a lot of stuff go. Things just got worse and worse over the years. Now the entitlement is crazy.
I had a neighbor who also did everything you suggested. She moved out years ago with a nasty thing to say about each of the neighbors.
For some people, being nice only allows them to be more manipulative and try to take advantage more. I wish I could still be the "nice" neighbor, but at this point, my safety and peace of mind are at stake.
Looking back at the things I did as a kid to my neighbors, I live with feeling bad for how much anguish I caused them. I didn't realize it. I remember riding my bicycle on my neighbor's garage floor because it had a smooth finish, dragging oil on the floor all over his garage in ugly loops from my bicycle tires that he could never get out. He told me he'd call the police. He was livid. If someone had told me how much pain and stress I probably caused that guy, I might have been a better human being.
