That is to say, Hello from Sweden!
English in Sweden is interesting because (besides being impeccable) it more often sounds American than British (at least in terms of vocabulary). My former Swedish tutor attributed this to the fact that Swedes get a lot of their English from television, and most of that English is American. In fact, flipping channels on my hotel room television (which gets Swedish, Danish and German channels), my choices now include a Will Smith vehicle, Lost and MTV's Jackass, subtitled in Swedish (or Danish, depending on the channel--I'm on that end of Sweden).
While Swedish English is usually very natural, I was initially puzzled by the following instruction, embossed in the control panel of the elevator/(BrE) lift in my hotel:
INSERT ROOM KEY TO DRIVE CAR
In AmE, the 'box' part that you enter in an elevator/lift is called a car, and according to the British information on lift/elevator safety equipment that I can find on the net, they're called cars in BrE too. However, when I tried to use car as an example of polysemy (multiplicity of meaning) in a semantics class in the UK, my students told me they'd never call a part of a lift a car, so perhaps it's not a well-known term in BrE. Anyhow, while/whilst it's correct to call that thing a car in (at least American) English, it is not idiomatic AmE to drive the car of an elevator. I think that such an instruction in AmE would read "Insert room key to operate elevator" (or, more probably, "To operate elevator, insert room key").
But talking about this Swedish sign is just a weak introduction for talking about "Signs You Wouldn't See in America". Of course, there are many signs in the UK that one wouldn't see in America. The speed limit signs look different, the (AmE) YIELD signs say (BrE) GIVE WAY and, of course, there are no signs in America for Ansty Cowfold. But I know people like reading about taboo words (if the number of comments on the toilet post are any indication!), so here are a few more for you.
This picture, advertising an event on my (BrE) uni's campus, would of course not be seen in America, where people would have made sure to abbreviate association as Assn or Assoc. (Go back here for discussion of ass/arse.)
Another one, which I haven't managed to capture in pixels (One used to say on film... What does one say now?), is at the local Bon Marché (BrE) shop/(AmE) store. This company, which sells inexpensive, larger-sized women's clothing (and which, as far as I know, is unrelated to similarly-named companies in the US), has recently taken to re-branding itself as BM, and offering the BM Collection. (Americans, stop your giggling right now!) As my brother Bill will tell you, you don't want to be a BM. When he has to initial things, he uses his 'proper' initials WM, because of the tee-hee-hee factor of BM. BM, you see, stands for bowel movement. In other words, it's a way to avoid saying shit.
