It's fun to call my friends and family at 6PM eastern time and scream "Happy New Yeaaaaar!" drunkenly into the phone.
Sometimes if New Years happens to be on a weekday, they are actually still at their jobs working when they get my obnoxious call. That's right, while my Yank friends are in their cubicles printing TPS reports, we in France are already on our 2nd or 3rd bottle of champagne. I almost feel guilty. Almost.
