The phone is a little creature we stitched together from craving and convenience, then acted shocked when it demanded attention. 'Put it away,' says the teacher. 'I need it,' says the pupil, thumb already twitching. The guidance wants a phone-free day by default, even during breaks, because the monster feeds in the corridors as much as in class. If adults enforce it calmly, the creature starves; if adults bargain, it grows clever. The cruel part is not the ban, it's the relapse, when every ping outside school yanks them back. So yes, lock it away inside school, and stop telling yourself that a child can outwill a machine designed to hook them.
