Some rando English teacher gave her students pot brownies, because she was fucking bored with reading Romeo and Juliet. This BSCB decided that instead of just doing her job, she would make weed brownies and give them to two girls in her class. I'm assuming she chose those two girls because they wrote the two best essays about themes of individuality in The Scarlet Letter.
Then, the girls told their parents about how they were super high for the whole day so the parents called the headmaster and he was not super happy about it. The teacher quit, which is a stunningly good choice considering her track record of being fucking crazy.
