zombies

The whole class had gone silent because they heard the noise that indicates an annoucement was about to be said. They waited a few seconds for the annoucement.

"This is not a drill. We are going to go on lockdown teachers lock your doors. We have been informed by the government that their are zombies nearby. Do not let any of your students out until it is safe. I repeat do not let any of your students out of the classroom until further notice. Thank you."
