Two empty classes
Today I got called to substitute teach school that I have never visited before. I would guess by now I have substitute taught at about 12 different schools. Usually they're fairly close by where I live in the school district. It would take about a half an hour to get to the school. Most of the reason for that is the slow speed limits of the schools.
The thing that was more concerned with it knowing told me the first two classes of the day were open. That means it for two hours I had to sit still and wait for the third. Class to arrive. It would've been nice to have been told ahead of time. But that's okay I will still make the best of it and it will make it a shorter day overall.
