I'm currently writing in 1st person (and want to continue to do so), and have an incredibly clear characterization in mind for the narrator's best friend (too much of a wildcard to write intimately), but I feel that in doing so I'm neglecting the MC as it were, and that she serves no other purpose than to describe the people and goings on around her. Her observations are very emotionally astute, and I know that sometimes a deep empathy with others can breed introversion, but I can't help but feel that any insertion of 'personality' breaks up the flow of the writing and feels forced, like I'm putting the brakes on the whole thing in order to shout 'and she's a big fan of cycling and enjoys chocolate chip cookies!'. I want the general feeling of the book to be one human being observing many others, and I don't get the same feeling from writing in 3rd person. Then again, I feel as though perhaps I'm simply inside her head too much, and can't see the personality that develops from hearing her internal monologue? Does anyone else feel a little guilty for sidelining their main character and falling in love with another?
