I met my wife, Cece, in 2014 at a music-video shoot in Austin. A mutual friend invited a group of us, we got talking, and we had our first date the next night. Two weeks later, she flew to Australia. After nine months of long-distance, she moved to Melbourne for good. I'd always assumed Australians and Americans were basically the same. We speak the same language, watch the same movies and TV shows — but more than a decade into this relationship, the small differences still catch us off guard.
