Everyone taking the girl's side as if they know the whole story.
If she really wanted to be taken seriously, she should have spoken to the teacher one on one and addressed the issue, not have a meltdown to give the rest of the class a laugh.
I went to high school with this kind of girl, the ignorant, loud and obnoxious girl who always wants to cause a scene and pretend like they want to learn but really they just want attention. The teacher is clearly a pushover if he allowed that kind of behavior therefore you know she was just trying to look like a bad ass. Bitch, please.
Even IF she was right, she's still wrong because of how she handled it. It's never cute to act that way.
