Then there is Sonny, who, when he’s not whizzing by at the mall (no one could keep up with him), volunteers at Sinai Hospital. Without breaking stride, he always greets me and others by name. Of course, there also is a woman who usually walks alone, looking angry and greeting no one. And there are others who only talk to one or two people. But the world would be a lot nicer if there were more people like Marty or like Doug, another walker, who, before he retired, worked in Parks and Recreation with former Mayor William Donald Schaefer. During intermission at a recent BSO concert, while Doug’s wife Florence and I chatted, Doug was greeting what seemed like half the audience, those he knew and, I am sure, others he didn’t.
