In the UK, on the 11t h hour of the 11^th day of the 11^th month, the nation commemorates those who served in World War I and II with two minutes of silence. The 11-11-11 marks the time of the signing of the armistice that ended WWII. This shot was taken in The Tube, where those on the platform either stood silently or quietly went about their way. As you note, most folks are wearing poppies that are sold with the proceeds going to war veterans.
