I was in Physics lab during the last period of the day of my senior year in HS. We were directed to put away the various combustibles and explosives and go home.
My parents always told me of the two days that they had photographic memory of: Dec. 7, 1941 and April 12, 1945, the day when FDR died. For me, November 22, 1963 and Sept. 11, 2001 are those two days for me.
