The holiday Memorial Day weekend is upon us and this is when we remember and thank those fallen heroes that died fighting for our country. This honorary day is celebrated across the United States of America on the last Monday in May. On this day many people visit cemeteries and memorials to honor all of those heroes with many volunteers placing an American flag on each grave. The U.S. flag is raised to the top of the staff and then lowered to half staff, where it stays until noon. After that, it is raised to full-staff for the rest of the day, which is symbolic as the flag rises and so is their memory by the living who promise to not let their sacrifice be in vain and continue to fight for liberty and justice for all.
