Memorial Day is an American holiday, one of the few days that most Americans don't have to go to work (although those in the retail and restaurant industries have to work, but get higher pay). The TV news carries images of soldiers paying Taps, which I think are heart-wrenching no matter what side of the political spectrum you're on. Local neighborhoods often have parades.
Americans are also expected to place flowers on graves that they've neglected throughout the year.
Was today an important day in your culture? What did you do in rememberance?
