Lots of things should be forgotten, otherwise we could not continue as human beings but would end up a mindless heap quivering in the corner of a darkened room. However, some bad things we should not forget. Days like September 11, 1939: Germany invades Poland and WW II begins. September 7, 1941: Japan bombs Pearl Harbor. June 6, 1944: D-Day when the Allies landed on the beaches of Normandy and the word Omaha became more than just black marks on pieces of paper. The USA lost more than 3,000 men on that one beach from V Corps alone. All total, the allies lost 120,00+ men at Normandy.
So, Next Week, on the 6th of June, Sunday Morning, remember D-Day and the sacrifices made by the ordinary men who wore USA and USN uniforms in order to keep your freedom, your way of life.
