I was fortunate that we all settled into one ethnic neighborhood, literally in the same parish, and we all lived in near-to-each-other family owned two-flats; all walkable, only a block or two away from each other. This meant that I was taken care of during the day and after school by my grandparents, and spent close time with them all of the years they were alive, even as I entered young adulthood.
If you lived in my parents' house, you were expected to "spend some time with your grandparents" at least every week. Didn't matter your age. And their sidewalks better NEVER be left unshoveled! There's something special about those grandparent-grandchild relationships.
I very badly miss the toughness & strength of that WW-II generation. But most of all, I miss their conviction to always do the right thing. They just seemed to always immediately chose to do the right thing, no matter how hard or how dangerous, without a second's thought or the bat of an eye. They did it instinctively and from rote behaviour, it seems. They also were patriotic as hell, and really loved America. Why wouldn't they? America saved them and their lives and the lives of their loved ones back in Europe, when Hitler was grabbing them up.
