Joe had felt it reasonable to call classes for day a loss, at least when it came to learning anything about divination. Even if he'd been able to get everyone to stop playing with their patronuses long enough for them to pay attention, the patronuses themselves were way too interested in playing with each other to allow a calm and quiet teaching environment.
So Joe said fuck it and and spent the entire morning playing with his gorilla.
Walking into the Great Hall, his gorilla loped behind him, occasionally bumping its knuckles into Joe's shoulders and wrapping his fingers around Joe's wrist. It was a little bit like having a toddler at his side, but one that happened to have the capacity to smash one of the benches in half if ever severely provoked. Joe kinda liked it.
