Let's write!

Go back and look through the fills you've created for this community and select one that should be part of a larger story. Now, either write what happens next or write what happened previously. It doesn't have to be long - maybe if the original scene was two people talking to each other in a parking lot, the next thing that happens is that they both walk off to their own cars and drive off - but it should feel like it leads on to the rest of the story or leads from a previous unwritten part into the scene that you posted. Basically, this is encouraging you to take an idea and develop it out further.
