April 17, 2014. Greeted Mama with a birthday cake as soon as I woke up. I had secretly bought one the night before when I went out with a friend. It was our last day in Sydney, and we had the day to ourselves, no tours booked whatsoever. Guided with GPS and Google Maps powered by prepaid mobile internet on my phone, we wandered around downtown Sydney, did a few shopping, before hopping on our ten-hour train to Melbourne.
