Neighborly behavior
Unfortunately, disputes between neighbors are all too common. When you share a yard, a fence, or even a street with another person, a lot can get in the way. Neighbors can be dirty, noisy, and otherwise inconsiderate at times, making it difficult to turn the other cheek and walk away when you live adjacent to one another.
When dealing with an inconsiderate neighbor, what do you do? Some choose to go down the higher road and bring peace offerings, while others pick to administer their own medicine. This person ignored his neighbors as if they didn’t exist, which is why he (very plainly) cleaned just his side of the fence.
