To fully understand the difference in writing a narrative point of view versus using dialogue, one must look at the way it is written. First look at the definition of the two. A narrative is the way a story or set of events is portrayed using descriptive accounts and experiences in either the past, present or the future. The story evolves around one or several different characters but is usually told by one person overlooking the events as they unravel. A narrative is told in this fashion for entertainment or informally to tell the story.
Now lets look at dialogue. Dialogue is usually written as a conversation between two people sometimes between one person talking to himself. This form of writing is much more fun and is used more to portray the characters in a certain likeness. If their speech is poor, you assume they come from a poor background. If they used refined elegant speech, you assume that they have been well educated. It’s funny how reading something can show different perspectives according to the actual reader. If the reader is in a bad mood, they might see the whole story as having a dark tone. The opposite can happen if they are in a good mood. The reader has to observe the characters in their own view, as well as the way the writer intended them to be. If a writer tries to write a book for teenagers, they have to limit their vocabulary usage especially if they are much older. A person’s vocabulary is always changing from an early life until adulthood. Not two people on the earth have the same exact vocabulary. This shows how differently one person can perceive a story from another person.
One person might hate the story all together and think it is beneath them. Another person the same age might look at the story and really love it. Narrative writing is much easier to understand because the writer has more control over the intended understanding of the reader.
