I appreciate your sentiment but people don't say "Happy" Memorial Day. It's not a happy day.
Memorial Day is a day of remembrance to honor our war dead. It's not a day to celebrate.
Traditionally, the American Flag is lowered to half staff/mast from 8 a.m. until noon. Then, it's raised up again. Also, people decorate the graves of military veterans with small American flags, wreaths, or flowers.
Tell us the truth about Benghazi!
