In the bookstore across the road from the one where I got my English/American dictionary. At least we spell in English. American is an entirely different language - like the difference between Dutch and Afrikaans. We can understand each other, but the language isn't quite the same anymore.
The Dutch can understand the South Africans, but just barely sometimes. American would be just as confusing to Aussies and Brits were it not for Hollywood - we're exposed to it constantly.
