She obviously grew up in the age of the internet when children did not have to resort to the photo spreads in this stellar magazine for pictures of naked people. Hey! I'm younger than your youngest coworkers but I, too, had to resort to National Geos for nekkid people. Or near-nude people, like the penis-sheath-gourd wearers of Papua New Guinea. Though I wasn't old enough to share my discoveries with others, or to turn NGs into an euphemism ;D
Ahem, I digressed. So, what an absolutely UNIQUE way of borrowing special cultural practices to foil Nagini. Though National Geos weren't mentioned in the books, it isn't inconceivable to think that a wizarding version of the mag exists. I mean, it's obvious that some of those absolutely breathtaking photos were taken with the aid of wizardry, right? ;)
