You don't have to be a detective to solve a mystery. Just ask the right questions and keep your eyes open.
We were all wondering how the administration knew which teachers were late and which were on time. Many suspected cameras. Some suspected that their own AP was taking attendance. None of these premises are right. I figured it out today.
When we sat down at the plenary session, AP's walked around and collected our attendance sheets. People that walked in after the collection were handed the same attendance paper and told to fill it out and drop it in a box. Everyone did just that. No one suspected anything unusual was up. So now the administration new that everyone in the box was late and they were the ones who got the letters. Pretty sneaky!
I hope the administration can think up the same kind of devious methods and go to the same extremes to keep the kids in line.
