I was in 5th period English at the time. There was a knock at the door; and our teacher Mr. T answered. When he came back, he told us “Somebody shot Kennedy.”
I went to a college which at the time was all-male. By edict in the dorms, every weekday night from 7 to 9 were “quiet hours”. It was self-policed and worked really well. One might hear an occasional noise at other times. But during those times, tombs were noisier.
Now the pessimist has even more reason to be that way.
