Knowing Your Neighbors

I read an article that said most people don't know their neighbors. Asking for myself: What's the point in knowing your neighbors? I can't see any benefit to knowing those who live beside or across the street from you. You mind your business and I'll mind mine, and all is well in our neighborhood. Some neighbors are nosy, messy, or have bad vibes; then you have those neighbors from hell. I prefer to live low key, where very few or nobody knows me because you keep out drama that way. I only know one neighbor, she's an older woman who's real chill, so we chat from time to time. I'm just saying that all neighbors aren't good neighbors. The minute something happens at your home, your neighbor probably has something to do with it.
