Recently-ish, we had some upheaval in the neighborhood as one neighbor moved out to a bigger house and the other neighbor died (the two houses either side of me). It was rather nerve-wracking as the block up is really bad (meth house burned once, there's constantly a lot of evidence of drug trade) and just don't want that coming any closer to me (I own the house free and clear as an inheritance).
So the one side was sold in an auction, and the mother and son who moved in may have a lot of health issues, but they're decent people. Then today, middle son was out in the front yard mowing when he sees our hairdresser drive up to the house next door. Turns out our hairdresser's mother is going to be our new next door neighbor, and the hairdresser is also planning to move in. Yay, back to having good neighbors on both sides of me.
