I go to Sams Club frequently and there is the greeter and the security "counter" of merchandise as you exit. They are usually older than I am and I enjoy their smile, exchanging hellos or brief comments, and their drawings on the receipt for Ellen.
Today, at exit, my friend (I don't know his name) announced this will be his last day. He is now 80 and "the time had come". He was not being forced to retire - it was just his time. The line began backing up so my further inquiry could only be brief - "God Bless You".
It's the people on the edge ( and not edgy people) that we see day to day that create a feeling of community. We don't know their name but there is a bond - a smile, a nod, or even brief exchange of words.
