# It completely escaped my attention that it was Friday the 13th. I'm not superstitious about it anyway.
Some believe the origin of 'unlucky 13' comes from the Bible as Judas was the 13th guest and betrayed Jesus. In Norse mythology, Loki ruined a dinner party of the gods and plunged the world into darkness; yep, he was the 13th guest.
An interesting parallel there.
Friday has long been considered the unluckiest day of the week. Put the two together and you've got a perfect storm.
