Character Interaction

Let's keep this section brief and to the point for right now.  It is advisable to keep your interactions to two people for the first quarter or so of your story.

During this phase of your work you are essentially defining your characters.  The best way to do that is through contrasting features.  The protagonist, or central character gains definition not only by who she is, but by how she differs from the character she's interacting with.

If your story has more than two characters, the contrast of personalities is washed out.  The clarity and focus upon the main character also is lost.
