Having no kids at home to celebrate them with any more, I don't bother with Christmas or Halloween much these days. Gone are the days of spending hours putting up Xmas trees and decorations.... gone are the days of being woken up at the crack of dawn by excited kids telling me that Santa had been. We do get presents for the grandkids, and we do have a special Christmas dinner, but after that it's just another day for me. Shoot, I don't even celebrate my birthdays anymore.
I do, however, celebrate on New Years Eve, like out with the old and in with the new, but generally speaking there aren't as many New Years skins to mark the event. Not that I celebrate it personally anymore, Easter is one holiday that I'd add to the list. Plenty of people do celebrate Easter and I do recall seeing some skins to mark the event.
