Why do these script writers not do their homework or at least allow for intelligence interaction when dealing with a plot twist?There is nothing more frustrating when watching a movie to come across some of the lamest interaction with the characters.Case in point with Frieda and the parents discussing her calendar and keeping track of these lying female students and regarding their time of the month.But Noooooo it couldn't be that easy to explain the reason for double checking these girls who appeared to be having their period twice a month.Or that one or more of these students broke school policies by taking this personal calendar, defacing private property and posting it online.
