Neighbors have the power to make or break your daily life. A good neighbor, who is quiet and takes care of their property, and might even collect your mail while you're away on vacation and not even open it, is an absolute angel. Unfortunately, they're also pretty rare.
But so, thankfully, are the very worst of neighbors, who just don't have any regard or respect for others or even their own property. It's not uncommon for neighbors who don't have any sense of common decency to find themselves embroiled in neighborhood wars.
