Relief....
I walked into school on a HOT Sunday afternoon. The building was sweltering as it is not air conditioned and has been closed up for the summer. I reached out and put my key in the keyhole. I turned it, wiggled it, and tried to turn it again. Success! My hand then moved to the knob. I slowly turned the knob and opened up the door.
RELIEF!!!!! My classroom was set up how I asked them to set it up. Now the real work can begin.
