There was no specific requirement for being a twenty-something—it’s what I found so disorientating about the experience. I never knew where I was meant to be or what I was meant to be doing—it was just as normal to be a twenty-seven-year-old with a husband and a labradoodle called Brie as it was to be one who lived with strangers from Gumtree in a basement flat with no living room.
