I’m writing these words as an American, located in the United States, thus the use of the “we” pronoun. If you are in fact reading this and you are *not* American and do *not* live in the United States, it won’t quite be applicable. If you are perchance European, then I would rephrase the question, thusly: Why do youse guys get all the Christmas Monsters and we don’t?! What makes you so special? Huh?
Okay, we here in the States get Monsters, too, sure, just not as many. And we don’t appreciate them the way you all do over there. Here I use “we” collectively. *I* for sure appreciate them. Lots of us do. But not as many as do you European people. We’re starting to. We do love us some Krampus nowadays. He even got a major Hollywood movie, you know. But only the scholars over here know about Black Pete or Pere Fouettard.
There’s more. From the linked article: “Like relatives returning home for the holidays, more monsters show up with increasing frequency as Christmas approaches. Every night from Dec. 12 until Christmas Day, the trollish Yule Lads peep through windows, snatch sausages and gorge themselves on stolen skyr in Iceland. On Dec. 25, goat-footed Kallikantzaros goblins emerge from underground and demand piggyback rides in Greece, Bulgaria, Turkey and the Balkans, and Germany’s Frau Perchta creeps into homes to slit open bad children and stuff their bellies with straw. Both do their mischief throughout the Twelve Days of Christmas until Jan. 6, when Italian children finally hang their stockings and the witch La Befana shows up with lumps of coal.”
Why aren’t these figures as much a part of American Christmas lore as they are for Europeans? Blame Santa Claus, says the linked article. I’m not sure I agree with that, but it’s as good an explanation as any.
