Your language structure is also less evolved... I know we speak almost the same, but the way "American" is built, gramma wise, and so, it's about 3oo years behind the brit's... Most peeps don't know this... But "American" is more "primitive" than "british"... Sorry I had to use such strong words, but there simply is no other way of saying it...
An NO, I'm not just saying this to mock you yanks as I so enjoy... I'm quite serious!
The the differance is minute to say the least, and no one would ever know the diff was it not for your horrible accent's (sorry, but the letter "R" was NOT ment to be prenounced like that!

) and the fact that we have a ridiculously large ammount of slang, that you lot don't ever use... and our word play... appart from that tho...
Sit's back, and awaits to be horribly flamed...
