I was in 7th grade and was anticipating the Friday night basketball game that night against our most hated rival when the school's PA system came on, broadcasting a radio report. There were a lot of puzzled looks at first because that never happened before. Then it became clear what was happening. My homeroom had a TV in it (one of just a few in the building; it was the first year our school had them), and for the first time ever it got turned on and our room filled up with students to watch the coverage. Of course everyone was shocked about it and many people were crying, some uncontrollably. My most vivid memory of being in that room was when I glanced behind me and saw my homeroom teacher behind the mass of students with a big smile on her face. I had never liked her as a teacher, but after that day my respect for her as a human being went right into the toilet. Maybe she was trying to show courage and calm in front of us students, but if that's the case it went over like a lead balloon.
The game was cancelled of course, and everyone's world shrunk around TV sets for the next few days, and that was all that was broadcast on the 3 networks. It was all so shocking and depressing, and then when Oswald was murdered by Ruby in front of millions of people (including me) a new level of shock and confusion followed. "What the hell was happening to our country?" was on everyone's mind. Nothing felt the same after that day.
