The festive red envelope is emptied from the mailbox by the postman. He drives it to the distribution centre for sorting, where it goes to the "Really Really Urgent" pile despite the fact that only regular postage is affixed.
Marty McFly picks up the envelope and carries it to his silver Delorean. The red LED's in the dashboard read, "Australia. DEC 25 2006".
He hits the gas and the car hurtles down the road. 60 miles per hour. 70 miles per hour. 80. It reaches 88 miles per hour and the Flux Capacitor kicks in. The car vanishes in a trail of flaming rubber.
Thousands of miles away and almost two weeks in the past, a postman deposits the red envelope in the mailbox of a house near the beach in the town of Avalon, just outside of Sydney. The owner of the house opens the envelope and a feeling of holiday cheer washes over her.
... at least that's what I hope will happen when I send Kay her Christmas card today. Hooray for procrastination.
