Santa Claus is really just karma with a red velvet suit; thus, Christmas is really just Halloween for Karma Claus. AND since all the presents (or coal) arrive on the 25th, then we might as well label it our annual Judgement Day. And it could be that Black Friday is just a testament to how thankful you are for the non-tangible things in your life.
Eh, just a theory. Merry Karmaweenmas!
