Most of the old-timers have died and a few new people have moved in, but we still wave, even to unknown cars passing by when we are sitting outside. Southerners still invite people to sit down for dinner (lunch) occasionally, especially neighbor helping neighbor do something. A few years ago we invited two pest control guys to eat with us, didn't know them, but anyone with manners is invited. Ma'am and Sir are refreshing greetings these days. (There are no cafes or restaurants around here.) I deliberately make some people be friendly. I whispered to a dignified bank clerk Friday, "It's spring!" and she had the biggest grin and said, "I know!" I've noticed that when I feel especially good, people tend to be friendlier toward me.
