Many of us do not know who lives next door. It is often difficult to break through our constructed barriers of paranoia, distrust, and expectations of privacy. Knowing your neighbors is the most basic building block of creating a livable community. Don't get tripped up about how to best develop the relationship. It's easy to know when someone could use a hand. If your neighbor is using scissors to cut his grass, and you have a mower...just bring the mower over. He'll be watering your tomatoes while you're away before you know it. Plus, who knows what you'll learn in the process.
