You stupid fukk.A teacher has the right to take your phone if you are using it to disrupt a class, breh.
At the start of class the phones were taken from all of the students so that they wouldn't cause a distraction in the class.
At the end of the class, the teacher refused to hand the phone back as punishment for the kid's alleged bad behaviour during the class. Regardless of whether or not the kid misbehaved the teacher was acting outside of her authority.
Your bitterness towards the next generation is so severe that you're caping for some uncouth leggobeast.
