You perpetrated one of the earliest acts of extreme inappropriateness that I can remember. But really, you could hardly be blamed, for you, like me, were only a child at the time. Like the rest of us, you probably had only the vaguest awareness that the spaceship that had disintegrated that morning over the Atlantic Ocean had been carrying real-live people, all of whom were dead now. I can't remember if it was the same day or the next, but the teachers decided to show us a videotape of what had happened and then talk to us about it. We watched as the Space Shuttle Challenger launched into the sky, raced towards the heavens, and then exploded into a massive plume of smoke. The whole class was silent, but you had one word to say.
