I think something might have been lost in traslation mid Atlantic, Steve!. I recently learnt that 'your'e kidding me!' is much stronger in the US than here where it is a completely harmless phrase! Personally, I find these differences in language usage very interesting.

"Two countries separated by the same language." G.B. Shaw (attrib). ;)

Maybe GBS, but it's been attributed to quite a few different bods over the decades, Steve.
100 years ago philologists were certain that English and the American version of it would split irrevocably by about 2050. But they couldn't predict popular culture; Hollywood and popular music and television. The opposite is happening.

Indeed! Recording technology and mass communication in particular. I've seen it suggested that the maximum divergence was on the eve of World War I. Then came the doughboys; then after the war radio and movies, which exposed different parts of the Anglophone world to each others' accents and usages.
