Lock-Out!

Oh, the challenges of being a first-year teacher in an overcrowded urban school! Not only do I float from classroom to classroom, since I am too junior to have my own classroom, but I don't have a key to any of the classrooms I teach in. So I showed up to class today only to find out that it was locked. Nobody in the building seems to know how to open the door. So much for the test I was planning to give... I guess my kids are happy!
