In the weeks that followed, I not only wrote in Diva’s agenda, but I printed off lists of her missing assignments, progress reports, and letters home, and stapled them to her agenda. I did this every week, without fail, and Diva’s behavior did not change. By the end of the 3rd Quarter, she was missing 8 assignments and was failing my class yet again.
However, any principal I've worked with also knows this about the parents, so they put on a show to calm the animals down but trust you to do something to try shutting them up next time.
