Even though we both speak the same language, it's amazing how there are some subtle differences between American-English and proper English:
They say "sidewalk" we say "pavement"
They say "pants" we say "trousers"
They say "buried at sea" we say "naked and chained to a metal bed frame with a car battery connected to his bollocks whilst being beaten for answers".
Though you are French born, your perception of the subtleties of the English language are quite remarkable.
