…But why do you need an object to go to the bathroom? Does it unlock the magic bathroom door?
a hall pass is a thing you can show to school staff to prove you’re wandering the halls with your teacher’s permission, not skipping class. once upon a time it was a piece of paper, but people kept losing those, so around the time i was in high school, teachers started taping the school-issued cardstock hall pass to things like blocks of wood, plastic flowers, and plush toys, to make them harder to lose.
apparently it wasn’t enough.
