To all the people in the notes saying they thought that parchment was old-timey paper: you didn't write five fantasy books where it is explicitly mentioned as being used extensively multiple times each book. If you had, you presumably would've looked the word up in the dictionary first. Different writing materials require different types of storage and treatment and you'd look up parchment vs. paper if you were going to replace one with the other, to make sure you didn't make any stupid worldbuilding mistakes. Same as you would with vellum, or papyrus, or wood slips, or any other writing material.

you would be amazed and depressed to realize how confidently wrong most writers are about at least one crucially important item that made it to publication.

Another thing JKR did that bothered me as someone who volunteered at a raptor centre before I read the books (I was late to the party): the casual ease with which everyone handles owls.

The thing about owls, and raptors of any kind, is that they have big fucking talons. And it doesn’t matter if they're trying to hurt you or not, these are animals with meathooks on their feet. You need special equipment to handle them without risking serious injury and infection. You at the very least want a falconer's glove, but given that owls like to perch on your forearm like it's a branch, you're better off with an eagle glove which covers your whole arm.

At no point in the Harry Potter series is falconry equipment of any kind ever mentioned. People just let owls perch on their hands or shoulders like it's nothing. There's even one particularly cringe-inducing sentence where an owl sits on Harry's lap, a glaring continuity error in light of the epilogue where he has children. I could only conclude that standard wizard clothing universally includes thick leather gloves, shoulder pads, and a jock strap. That's the only way I could get through it.

"There's even one particularly cringe-inducing sentence where an owl sits on Harry's lap, a glaring continuity error in light of the epilogue where he has children."

This is the funniest thing anyone has ever said about Harry Potter

An update:

For some reason, Patreon appears to have moved its payment processor to Ireland. This is causing some American banks to see payments routed internationally and they're flagging the charges as fraudulent.

Just a giant damn mess.

This is weird. (Especially since Patreon used to have offices here, for a few years, but closed them last fall.)
