That is kind of a silly argument unless your kids are allowed to wear sunglasses in class or listen to music. Are they? If so I would suggest showing your parental outrage right away. That is very poor classroom management

In fact if you are correct about sunglasses and ear buds this makes the damage done by masking even worse. So let’s ban all of it
