I remember meeting a bunch of Argies once, they had guns and knocked on my door, expected to be welcomed in and could not understand why we were listening to the BBC. They were even more confused when my parents told them that we were British. It was April 2nd 1982!

My country will always be the Falkland Islands and one of the most proudly British places on the planet.
