The “you tell, you’re a snitch” culture is still so prevalent
When I was in high school, a popular upperclassman took photos of the textbook/powerpoint on his phone in front of the whole table (the teacher wasn’t looking) and during the test, took out his phone and proceeded to use it for the entire rest of the class period. I saw him take the photos, and his phone even made a Siri sound during the test. This is a common occurrence at my high school.

I didn’t want to tell the teacher because I was scared that the cheater would proceed to rally his friend group to ostracize me. My friends encouraged me to, and in the end I did.
I was so scared to even show my face at school after that, for the following weekend I spent almost every waking minute worrying about what would happen.
