We talked about our parents and our siblings, our work and friends, our schools and childhoods, the implication being that we would need to know this information for the future. Of course, after nearly a quarter of a century, the questions about our distant pasts have all been posed and we’re left with ‘how was your day?’ and ‘when will you be home?’ and ‘have you put the bins out?’ Our biographies involve each other so intrinsically now that we’re both on nearly every page. We know the answers because we were there, and so curiosity becomes hard to maintain; replaced, I suppose, by nostalgia.
