Every generation has a "day" that anchors their history. For the "greatest" generation it was Pearl Harbor Day. My kids' generation looks back to 9-11-01. Baby boomers claim November 22, 1963 - the day President John Kennedy was assassinated. (Second to that day might be the Beatles' appearance on the Ed Sullivan show.)
We ask each other, "Where were you?"
I found out he had been killed when our school bus stopped to let us off. Our next door neighbor, Mrs. Fioriti, came running out to meet us, tearfully crying, "President Kennedy has been killed". For a third grader that was a lot to process.
If you were around on 11-22-63, where were you?
