The Hot Pepper

I would flip it.

I’d flip it too- always do actually. Sometimes to see who makes it if I like the card, or if there's artwork to look for the artists name, date it was made, etc. I think flipping/looking it over would actually be a natural reaction to a ‘What the…’ type scenario!

Yep, as Alchy says, "both" seems like the most natural reaction.

If it's a language learning school and they say "WTF?" then maybe they are in the wrong school.

Well its marketing. So they may not actually be in the school. Send out holiday cards in another language, flip to the back and see why the heck you're getting cards sent to you in another language/get a translation.

Ohhhhhhhhhhh. I see. So it's purposely in a language you probably do not understand. It's direct mail marketing of the school, with their logo/info on it and all?
