As you say "American English". I'm not American so I'll simply talk and spell English. We've already renamed school years to start heading towards being the same as America and they'll be called grades not years in the no too distant. It's nothing anti American either it's just this thing of trying to be the same as another country that simply isn't needed. I just find it bizarre even the kids come home from school and they're using American quotes all the time utterly bizarre. But the you go!!
