Almost exactly two years ago, I landed in Perth, Australia, marking my final continent three months before my 30th birthday. My friend Simone, who I met in Dubrovnik the previous summer, offered to show me around her city while I was there. She drove me to a national park a little outside the city where we saw dozens of kangaroos in the wild. I was drawn to Australia since I was a kid, most likely because of the kangaroos, so this was so exciting for me. I don’t think I stopped smiling the entire afternoon.
