I don't know... this will be my fourth Aussie Xmas but it still doesn't really do it for me...
It's not snow I miss (I can't remember too many white Xmas days anyway...), just the wonderful atmosphere of Christmas at my parent's place.
Decorations, candlelight, long afternoon walk in the cold - all wrapped up in winter coat, scarf and gloves of course -, great dinner cooked together flushed down with lots of great wine... But probably mostly being surrounded by all my favourite relatives and having a good time together.
This year in particular I would have loved to see my sister (who is almost 5 months pregnant) and my little nephew who has just learned how to walk and wave. Haven't seen him since he was a tiny baby.
I would jump at the chance to take a flight 'home' this weekend and spend it with them. Not that I'm complaining, I will spend it with my new family instead and it will be fun - just not in a Xmas kind of way...
