What, right this second?! Popp always forgets about the sending stones. He's not from a time and place that does fast paced immediate contact.

"...Standing on your head's a traditional meditation technique where I'm from, and it's great at expanding how much magic you can store up at once. It's not that silly once you get used to it."

Popp has several dozen variants on the ways he complains about things, and this one is one of the more good natured ones. He's still inherently defensive over the way his precious teachers have taught him to do things, but this is a mostly performative display of grouchiness.
