The undercurrent affects my classroom. I can feel its tug and see its effects but can rarely locate the source or the exact flow. Cruel taunts and gossip are the culprits behind my students’ tears, stony faces—their anger and their fear. The ferociousness of the few vicious communications I have been privy to as a high school teacher caught me off guard. High school can be a shark tank and the blood flows with every passing class period, thanks in part to the popularity of online social media. I feel helpless to save the victims because I don’t even know who they are half the time.
