It's amazing that one hour of teaching a day can make you feel like you've run a marathon and then had the crap beaten out of you by a passing thug.
Today was funny because we got into some bureaucratic ridiculousness. The school is on the 4th and 6th floors of a building used for other purposes. On the sixth floor, the school janitor does the classrooms, but another guy does the hallways. The school janitor "doesn't do" the 4th floor, so you have to appeal to yet another janitor. There have been disputes within my classroom about which janitor empties which trash can. Which is why I think hiring an independent cleaning company to come in once a day after school and just clean the damn room is probably a good idea. Entrenchment: not a good idea.
