Either/or. We had new neighbors move in on both sides of us. One side came over, introduced herself and gave us fresh green beans. The other side acts like they are in the Witness Protection Program. I took some mail of theirs that got put in my box over there and they were as friendly as a block of dry ice (and I’m reclusive). The new lady across the street btw is originally from South Korea and frequently brings homemade fried rice and spring rolls. Can’t beat that! Overall friendly neighborhood.
