I remember that day all too well.
I was in the 10th grade. We had finished lunch and waiting for 1:00 class to start. A kid who had gone home for lunch came up to a group of us and told that the president had been shot.
Kennedy was not popular in the Florida panhandle and most students seemed happy. After a few minutes the mood changed. I can recall several saying they hoped he didn’t die. Of course he was already dead.
During class the principal came on the intercom and announced he had died. The mood became much more somber. I recall a classmate who was a rare Catholic, weeping.
