I have endured the suffering of many Memorial Days in recent memory. Both my biological and step fathers were career military and have passed this earth. Not to trivialize my stepfather at all — but my biological father in particular had a very painful passing to witness in all my helplessness. Though they did not die in combat I still observe and honor their service on this day. They were both military retirees, as 'gung-ho' as it gets, and my closest family.
Memorial Day is one of our federal holidays in the United States. It is observed on the last Monday of May. It honors and mourns our military personnel who died while serving in the US Armed Forces. It's orgins are in a holiday called Decoration Day in those years following the Civil War. It is marked by visiting cemeteries, decorating graves, and participating in memorial events.
