In the offhand chance this is a genuine question, it’s because a large number of people in this country are essentially traumatized at the prospect of a pedophile, convicted felon, rapist, fascist in the white house, and schools know that students who are so preoccupied won’t be able to learn/pay attention in class, so they give them a break to allow time to focuse on processing the trauma from the election.
Could that be translated more colloquially to “stop busting my balls”?
