I'm back to normal posting, folks. I ran into some computer issues I had to take care of, but things should sail smoothly now.
To those of you who need to post next, there will be an announcement over the school intercom to stay inside the classrooms and lock the doors due to a security threat. The students and teachers will be asked to standby for further information. If the students look out the window, in a while they'd see cops showing up around the school. The teacher will close up the door, and class will stop. Do whatever you wish about the situation except leave class.
