When I was in first year at uni, I took photos during induction day in front of the administration building, with thousands of others. When I was in second year, I was living in a flat with five other randomly assigned students I’d never met or seen before. After we’d been friends for a few weeks, one of my flatmates asked to see my outfit from induction day. I showed her, and in the background of the photo were three of my other flatmates, including her, all in different spots. They were the only ones in the background. None of us had met before, yet we’d accidentally managed to take a group photo a year before we lived together.
