I was four also, and honestly don’t remember anything about it.
Well, like I said: I don’t really recall anything except the parents being very serious and focused at dinner that night. In fact dinner, for them, was on the couch in front of the tube. Which in itself was odd at that time.
And I do recall afterwards seeing the Life magazine cover with JFK in the car in Daley a plaza right before it happened.
That’s pretty much the extent of it. Until some years later seeing the Zapruder film late one night and going.... Woa! Up until that time i had never really seen “blood and guts” on TeeVee, either real or imagined, like we do today.
