Our current neighborhood is pretty quiet except for the people across the street. I don't know how they fit so many people into that house, but they do and they make more than enough noise to account for everyone. There are also several small children over there, from a baby on up to about age 12. When we first moved in ODS (who was 5 at the time) was playing with the next door neighbor kids. I guess one of the kids from across the street, who was maybe 4, was upset that ODS was playing with the neighbor kids and threatened to get a gun and shoot him. I went over and spoke to his mother, who was absolutely mortified. She made the boy come over and apologize and he hasn't been over to play since. (I wouldn't mind having him over to play but obviously I won't allow anyone to talk to my kids that way).
At one rental house we lived in, I was getting the kids ready for bed one night when someone knocked on the door. I ignored it since I don't answer when I'm not expecting anyone and went about my business. Put the kids in bed and the knock came again. I realized it's a "cop knock," so I looked out the peep hole and sure enough there are two police officers out there. They asked for some guy, I said I don't know who that is and he doesn't live here. They didn't look like they believed me--probably because I took so long to answer the door--and left. I was convinced they would be coming back but they never did.
At another house I was in the kitchen doing dishes when I heard the neighbors start screaming at each other. My kitchen windows looked out to their yard so I could see them coming out of the house, shoving and hitting each other. I called the police, who came to investigate, and the people apparently thought it was a great idea to sic their dog on the officer. The dog was put down.
Same house as the last story, someone stole a bunch of stuff off my back porch, including two bicycles. One was mine and one was my brother's old bike that DH was using. I was driving home one day and saw my two bicycles in the neighbor's back yard (different neighbor than the previous story). It was a rental house that my parents owned, so I called my dad and he went over and asked the tenant (who also worked for my dad) what he was doing with my property. The guy tried to claim that the bikes had come from his mom's house, but my dad flipped my brother's bike over and pointed out the ID sticker that my brother had put on years before, complete with our old home address in a different city. He didn't have much to say to that. I took the bikes home and the guy didn't keep his job for much longer.
