Why You Should Make Friends With Your Neighbors.

Peaceful Living: Neighbors who know you tend to be more respectful of you.
Safety: Good neighbors watch out for each other and their properties.
Back-Up Supplies: Ever been in the middle of baking cookies and realized you were a stick of butter short?
Joint Ventures: Friendly neighbors can plan joint flower colors, joint yard sales, etc.
Family Camaraderie: Neighborhood get-togethers and carpooling the kids to activities can be great benefits.
Family Support: Need emergency childcare? Not a problem if you are and have great neighbors.
Vacation Help: It's much easier to trade checking mail and watering plants with your neighbors than scheduling someone to do those tasks when you're away.
Social Circle (especially now): It can be nice to have someone nearby to socialize with, even if it's catching up over the fence for 5 minutes every day.
Good Advisors: Need to find a plumber you can trust? Maybe your neighbor knows one.
Business Networking: With more work-at-home businesses, your neighbor might need a Scentsy warmer from you, and/ or you might like the Mary Kay lipstick they sell.
Errand Help: A close neighbor will knock on your door to see if you need anything since they are running to the store anyway.
General Help: Life happens. Break your ankle? A good neighbor will help you mow your yard or bring you a casserole while you're laid up.
