Or maybe it wasn't. Almost the second I walked into the classroom, a voice came over the intercom simply saying "Attention faculty and students, we are entering a code red lockdown. Students on the playground, please go to the cafeteria." Fortunately, almost all of my 20 kindergarten and first graders were already inside.
We stayed inside for 4 hours. We weren't allowed to go outside for anything; not lunch, not recess, not even, sadly, to go to the bathroom. Fortunately, I only had one little boy poop his pants. Unfortunately, bladders are harder to control, and about 7 of the kids ended up having to go number one in a trash can.
Everyone seemed to have a pretty good time though, and to be honest, it was one of my better days subbing. I had an aide that was a lot of help, and the kids were quite good for being locked in a room for 4 hours without a hint of sunshine, and no lunch until the end. I think I'm actually thankful for the whole thing. Especially that I hadn't drunken a lot of water earlier.
