Hello again.. This is nothing to do with driving on the other side of the road. What is happening here is that we are all talking to an international group. You Americans are not just talking to each other here. No-one gives a damn if you say 11th Sept or Sept 11th ... but if you just use numbers... and reverse the order ... we don't know what the hell we all mean do we. I'm quite aware that we all do things differently like spellings etc and this is not a critism of any of that... its just about clarity of meaning.
