Whether you're celebrating Christmas, Hannukah, Kwanzaa, New Year, Solstice, Saturnalia, my Dad's birthday, or whatever, I hope any celebrations you have are happy, fun and safe.
Just a few things I've thought of: 1. Waking up and realizing I was only dreaming about being home. 2. Long layovers in Terminal 4 at Heathrow. It's a nice place, but not that nice. 3. Things I take for granted at home being hard to find or simply unavailable elsewhere. Jet-lag doesn't even make the list any more.
