While summarizing narratives we come across certain difficulties i.e. refering to first person pronoun, dialouge as sourse of conveying things to readers to name a few. It can be understood in an another way and that is, if you imgaine a passage of writing where communication has multiple layers in it. One can only assume one layer as the foundation and the rest of them would be explained through it, likewise in a narrative passage one has to assume one's position either in context of written passage or of the writer of the passage.
