In the Letters of the Angels, only one sign distinguishes curiosity from expectation – the last one.
While expectation always has a claim to fulfilment, curiosity is self-sufficient: the desire to experience something new, to get to know something new, can only fail if there is nothing new to experience. And this is highly unlikely. The opportunities that curiosity holds are innumerable – what counts here is the sense of possibility, not that of reality.
Whether the angels who turned away from heaven and towards earth treasured certain expectations? Who knows, they were curious in any case.
