Pick a date. Any date. Somewhere in the world, someone is celebrating it. Somewhere else, someone is mourning it. And somewhere else entirely, it’s just a Tuesday. Take November 11th. In France, the United Kingdom, Australia, and Canada, it is Remembrance Day — a solemn commemoration of the armistice that ended World War I at the eleventh hour of the eleventh day of the eleventh month of 1918. Poppies are worn.
