Crisis Z

The day flew by and I was sitting in my last class. I was in the middle of a test. There was silence until a siren went off. We do a lot of drills here one every week so I know every single siren but I didn't recognize this one. I sat so still trying to figure out which one it was. Then I slowly found it familiar. I had heard about it on YouTube. It was a zombie siren. No we're NOT in a zombie apocalypse. It was just weird I mean the teachers always tell us when a drill is going to go off so we're prepared and aware. I looked at my teacher and she was frozen but she was slightly shaking too. And that was the moment I realized that it wasn't a drill.
