How Do I Know That My Short Story Deserves To Be A Novel?

This is not an original idea.

I got this one from Robert McKee. It comes from his book, Story: Substance, Style, and the Principles of Screenwriting.

This is his test for testing a new plot.

Next time you are out with friends, ask them if you can share an idea for a story.

When they say "Yes," start at the begining and start telling the story. When you get about halfway, excuse yourself suddenly and go to the bathroom, gift shop, or phone.

Give it a five minutes or so. When you return, join the table and talk normal. Do not mention the half told story. Talk about something else. Act like you have totally forgotten that you were telling something before leaving the table.

If your friends can not stand it and they ask you to continue, take this as a good sign.

This could mean that you have an idea that others would enjoy.

On the other hand, if your friends never mention your story, do not take it to heart.

Do not take it personal, but rethink your story.

Remember how relieved you are when someone is talking and talking about something and they get inerrupted? If it this way with the story, leave it as a short story.
