Nia is chilling in the main reading room nearish where the Montréal kids hang out. On the floor, she knows she's not that in, but still. She is studying French and occasionally when a sentence of French comes to mind she will attempt to say it to someone but usually she doesn't since everyone is trying to study and wouldn't necessarily appreciate the interruption. Not saying sentences of French is kind of hard so after a while she switches to geometry.
"That's kind of a terrible question because there are some bizarrely creative uses of shields for, like, cooking and gardening, and these really impressively elegant spells, but obviously I'm not going to pick one of those, I'm obviously going to pick one of the ones that's designed to move groups of people through groups of enemies as safely as possible for a few minutes at the cost of literally everything else. And now this conversation is depressing and an allegory for our lives."
"Good to also know other things! As a nice to have. Not as a priority. Important to be good at priority."
"Yes! It is how you know that times needs managing. If you are bad at priority you go 'ah, it is time to trim toenails' and there goes an hour."
"No! Far too good at priority. But some people, not Scholomancing wizards but some, daydream while they do."
This seems like a much weirder claim than the existence of magic, but maybe his skepticism has made it impossible for them to do it in front of him.
"I kind of like the one for gardening where it not only keeps insects away, it also keeps you clean. At the same time, in one spell. I'm not sure if that's any less depressing, though."
"Does sound nice though! Clean only from dirt? Or clean clean? Second thing would be good in here."
