I stayed in my seat until everyone had gone, pretending the zipper on my coat was stuck so I could avoid looking anyone in the eye. Then I went straight to the computer lab to look up the word “Holocaust.” I don’t know how long I sat there reading about it, but at some point I’d read enough. I leaned back and stared at the ceiling. I suppose I was in shock, but whether it was the shock of learning about something horrific, or the shock of learning about my own ignorance, I’m not sure.
