Consider your story’s point of view carefully. If you really want the reader to relate to your protagonist, the story should be told through his or her eyes only, even if you’re using third person narrative. Avoid slipping into an omniscient viewpoint by including something your character couldn’t possibly know, such as what the other person is thinking, unless, of course, he’s telepathic. Instead, describe what your protagonist is seeing in the other’s expression and body language. Another way around this you can use occasionally is to preface it with, “He didn’t know it at the time, but….” Break point of view carefully, deliberately, and sparingly.
