I was in first grade and they sent us home, my only real memory of the day.
BUT...
We had just walked in from church that following Sunday, and my Mom went upstairs to change her clothes while my father snapped on the TV. No sooner had the picture burped to life than there was Oswald being perp-walked and up lunged Ruby and shot him. My father and I stood there for a second in disbelief, then I still can hear him shouting "Sally, come quick!" to my Mom upstairs.

THAT'S a vivid memory burned in my brain, and a transformative moment in the history of TV and America.
