I go to an inner city high school part-time and once a French class was so horrific that the teacher walked out in the middle of their period and simply never came back.
At the beginning 6th grade or teacher lost her voice and couldn't go back for the rest of the year. Then we got a teacher who we found out had been in a psych facility. The class would plan to go along with acting like she didn't have us homework or that she was confused on test dates. ...She didn't last long either :/
God - "LOL you want strength to strangle them or strength to put up with them?"
