The Principal came over the loudspeaker and said the President had been shot. I remember thinking, "He's someone important."
I also remember watching Oswald get shot on live TV...
I was also in second grade, walking back into the school building after having been outside. One of the other kids told the rest of us as we passed him. I can't recall if we were officially dismissed at that moment or if we went back into the classroom first, but I do remember walking home - it was a short distance - where my mom was watching events unfold on the small b&w television.
I remember there being a serious atmosphere in my little corner of the world that late November of 1963, but there was no hysteria or any sea change in the family routine.
