This time of year I miss eggnog lattes from Stateside Starbucks (I know sounds gross, but try one, they're yummy!). We have Starbucks here, but they don't have eggnog lattes (I never generally go to Starbucks here because coffee in Melbourne is the bomb, and Starbucks is blah). Australia doesn't mass produce eggnog (and really, do you want to drink eggnog when it's hot?). I also miss the holiday lights extravaganza that occurs in every neighbourhood in the States. People don't generally decorate the outside of their homes for the holidays here. It's summer, so lights wouldn't show up as much anyway, but I miss them nonetheless.
Australia's great, don't get me wrong. But between Thanksgiving and Christmas, I always get a little homesick for the the States.
