To cross the threshold is to enter another world-whether the one on the inside or the one on the outside- and we can never be really sure what is on the other side of the door until we open it… The crossing in and out, the different worlds, the significant spaces, are private coordinates that in my fiction I have tried to make paradigmatic… The story crosses the threshold from my world into yours. We meet each other on the steps of the story.
