I walked into my homeroom class in 8th grade. My mom happened to be a substitute teacher in my school that day, and she walked up to me, very obviously upset. So upset, in fact, that her vocabulary failed her, and she said to me, "The missile exploded." I very clearly remember thinking, "OK, so the USSR just launched their missiles at us, and everyone is about to die." My mom then corrected "missile" to "space shuttle" and I figured out what was really happening. It was still a horrible and shocking day, but I was actually a little bit relieved.
