Evading Death

"Hello everyone. Sorry to keep you waiting so long. It is unfortunate that I have to inform you that you all have to die now."

We sat in wonder and shock at the statement just stated toward all of us. 60 give or take of us were gathered in a school classroom awaiting instructions for the first class of the semester. We were just preparing our minds for a 4-month course, and now we suddenly have to be killed? All of us at once all together? This is absurd. Whatever could the reason be? We were never told.
We moved from this room to the next. Well, not all of us. A few lingered behind, to face their demise, and the rest of us moved on, temporarily escaping the death that has been fated upon us. Yet in this next room, our destination remained the same, certain mass death, a massacre of eerie sorts. A fewer amount of us made it to the next room, by random chance I suppose, still lingering on the edge of death's precipice. Many times this process was repeated, until instantly it was over. Had the moment come? Had Death arrived?
