One night, Hayden Starr returned home to find his neighbours having a party. He lived in an apartment complex in Canberra, with only one other unit on his floor, its front door just “a metre apart” from his own. Keen to see who lived there, he invited himself in.

“I grabbed a cheap bottle of wine I had lying around, go in and see this delightful, lovely girl,” he says. “And that’s how I met Sophie. It was her party, but we ended up spending ages chatting and she tells me all these crazy stories. After that I was like ‘oh man, there’s something about this girl. There’s something about this neighbour of mine.’”
