My neighbor stopped saying hello. He started picking up every package himself, even if he had to leave work early to do it. Then he put a small camera above his garage, pointed toward the shared driveway. I figured he was trying to send me a message. About a week later, the homeowners' association reached out again. They told me my neighbor had filed a formal complaint, but there was another part of his statement they wanted to discuss. He claimed my camera had captured a private conversation in his driveway. I asked when this was supposed to have happened. The association gave me the date. I opened my recordings and went through the footage. There hadn't been a delivery that day, and I hadn't noticed anything out of the ordinary. The camera showed two people standing near his garage for a few minutes, though the audio was too unclear to make out. I watched the clip again. One person was my neighbor. The other was a man I'd never seen before. They weren't fighting, and neither seemed aware of the camera. But right before the man walked away, my neighbor handed him a large envelope and glanced toward the street several times. I had no idea what the exchange meant, and I wasn't going to guess. I sent the association the relevant footage and asked them to explain exactly which rule they believed I had broken. Two days later, my neighbor knocked on my door again. This time, he had no package in his hands. He asked if I had shown the recording to anyone else. I said I’d given it to the association after he complained. His expression hardened. “You need to delete that video,” he said. I asked him why. He looked back over his shoulder, then dropped his voice. “Because the man in that footage wasn’t supposed to be there.” I waited for an explanation, but he offered none. Then he asked a question that made it clear this wasn’t really about a package or a camera anymore. “Did you happen to record what happened after I went back inside?”
