As folks look over their shoulder, they are reminded of events which hold particular interest, especially if they concern children, grandchildren and great-grandchildren.
As I stand on a so-called ladder of life, at my age I am pretty near the top rung. I observe my great-grandson, Steven, has advanced to the first grade.
Nowadays with all this pre-school and kindergarten stuff, seems he oughta be in the third grade by now. My ladder shakes, oh my goodness, my great-granddaughter Madison just began her first full day of kindergarten.
