What happened that April out in Colorado — two boys with guns and trench coats, thirteen dead, twenty-one wounded — quickly became known as Columbine. Just Columbine. I was in eighth grade and I didn’t yet know the word “synecdoche” but that’s what it was, the part become the whole. In May, a month to the day later, another boy with another gun shot six of his classmates in Conyers, Georgia. The school had its own name, of course, but this became another Columbine, and somehow all the others before it were Columbines too.
