I suspect we all sort of secretly think our lives are like these very long movies, with ourselves as the principal characters, obviously. Only very occasionally does it occur to any one of us that all these supporting actors, cameo turns, bit players and extras around us might actually be in some sense real, just as real as we are, and that they might think that the Big Movie is really all about them, not us; that each one of them has their own film unreeling inside their own head and we are just part of the supporting cast in their story.
