Whoever our narrator becomes, what we write is often 'lived' in a certain way, through a certain character and therefore with a certain subjectivity.
Take something you've (ideally) already written, something where the sentiments or viewpoint of a particular character or narrator is quite strongly felt. Imagine it from another point of view, a point of view that was overlooked in the original text, perhaps another character, a second narrator... you decide. Let your words live the telling from that other point of view. Change places.
If you feel like playing along, then post up what you've written on your blog and leave a message in the comments here - one (or both) of us will be over to read what you've written.
If you have any ideas for future prompts then let us know, we'd love to hear them and would of course credit you with it should the prompt be used.
