Memorial Day

Today is Memorial Day or when I was a kid my mom often referred to it as Decoration Day.  I know many of my uncles on both sides of the family served in various wars and I thank them for that.  I do not understand why the stores feel this is a weekend for big sales (well yes I do it is called greed).  So why do people shop and feed their greed?  I found this on facebook and I think it says how we should view this day.  We are still, for now, the greatest country and we need to learn who fought for this to happen.
