11-11 11:11
It's exactly 11:11 now. At the eleventh hour of the eleventh month in 1918, the guns fell silent after the bloodletting of World War I. When I was young this was called Armistice Day; now it's celebrated as Rememberence Day in some places, and as Veteran's Day in the US. It's a day to remember and thank and praise the ones who served, and still serve; the reasons they went aren't important.
Dad served in WWII, defending Britain as part of what later became the US Air Force. He never talked about it that I can remember.
