Is it possible to write a story in first person with two different perspective. I'm planning on writing a story about a girl and a guy but in FIRST person therefore I have to switch between perspectives.
It's possible and has been done. The problem is, it confuses the reader. You are better off writing this from a third person POV or write if from fist person and leave off the second person POV.
The remark I recall from a few days ago was, "It drives me crazy when first person POV has another person thinking."
It might come off more like a parlor trick than a real story, but then again it might be interesting. You'd have to be very careful to make the two different narrators distinct. I wouldn't trust to the reader to remember whose turn it is to be in first-person mode; make the voices unique.
R.L. Stevenson did it in "Treasure Island", where most of the chapters were first person from the view of Jim Hawkins, and some of the middle chapters were first person from Dr. Livesey's perspective. The tone was clearly different between the teenage boy and the middle-aged physician.
It's possible to do without confusing the crap out of everyone, though won't get very good votes.
However, if you were to break it up, tell the whole story from one person's view all the way through, then do it from the second person's view it likely will go over better, but then again, unless it's pretty darn short alot won't bother reading all the way through.
