Thirty years ago, I heard the news that John Lennon had been shot. Every year since, the morning news on NPR reminds me again of that day. I was a young, second-year teacher then, with four sections of grade nine “World Cultures” and one section of A.P. United States history. Mine was a Catholic school, and we’d had Monday, December 8 off because it was a holy day, the Feast of the Immaculate Conception.
