I once overheard an American talking to a Scotsman on a plane to Washington Dulles Airport from London Heathrow.
The paraphrased conversation follows;
<Scotsman> Soo. Ware ye be goin’ here?
<American> I been to, like, visitin’ Edinburrrgg England an’ all
How close this poor fellow was close to death I am sure he was totally unaware.
This diagram would have easily have remedied his ignorance, and will be a useful aid for expats like myself, who often get asked weird questions like “So… What do I put down for country? England or GB?”
