Another advantage of getting to know neighbors:
I have two people on one side of my house, both are even older than I am and handicapped. It's so painful for them to stand that they actively AVOID anyone talking to them outside (they would have to stand up during the conversation). But I got to know them a little anyway and offered flowers.
Always assumed I might have to help them out if they had some physical accident.
Well, one day I was shaky on MY feet but tried to pull a weed whose roots were stronger than my legs were steady.
I did a comical back-flip and smacked my spine hard against the driveway, while my head missed a concrete raised bed wall by about one skinny inch. My brains would have splattered.
I was still lying there, gathering my composure and strength to stand back up when the old gent limped over to make sure I was conscious and breathing.
Good neighbor!
(Even if he DID hire an idiot to spray persistent herbicide everywhere on his property and drifted into mine. he can't weed, hence the persistent herbicide.)
