Satellite year

At a party for the new year. The party is organized by the boyfriend of the roommate of a friend of a friend. I know almost nobody there. We arrive right before midnight and the place is packed. The basement is overflowing with people dancing to the rhythm of unfamiliar music. I will learn later that this is music is from Angola as most of the people in the house were either born there or have links to that country. There is serious dancing going on. It is 11:59 PM and I see everyone around me getting their cell phones out. It is a strange sight, everyone is still dancing but they're all looking at the cell phone in their hands. The moment their cell phone turns to midnight everyone shouts "Happy New Year!" Perfectly in sync, thanks to the cell phone satellite system.
