I was in 1st grade, so don’t have a great memory of the class announcement, but do remember sitting in the library watching the funeral (at least I think it was the funeral) on television.
What memory is forever etched into my mind was what happened at home. We had a housekeeper who locked herself into a small guestroom. She was distraught hearing the news; my mother could not get her to come out. Mom called dad at work, and after trying to talk her out, he kicked the door down! Instead of sending her home on the bus, dad drove her home to make sure she got home safely.
