Having neighbors can be a blessing or it can be a curse. Good neighbors can either make your life much easier or make it no different whatsoever. Bad neighbors, on the other hand, are a plight.
It's true that neighbor relationships don't have the same significance they had years ago. In the '70s, a third of Americans spent time with their neighbors at least twice a week. Nowadays, that same amount says they have never interacted with their neighbors at all, and only 20% regularly spend time with the people they live next to.
Maybe part of this is just that people want more privacy in their own houses? God knows folks get up to all kinds of stuff when they're alone at home. At least that's what it seems like after reading the comments under one online thread where one person asked, "What's the weirdest thing you've seen your neighbor do?"
