Remember to include scene transitions, especially when a significant amount of time has passed or the location has changed. Failing to address such details first and foremost can stall readers, causing them to go back and reread what came before, wondering what they missed. As the author, you know exactly what’s happening, but a reader may not if you don’t provide sufficient information.
If in the previous conversation your characters were talking about going to the beach, then picking up the next scene at the beach isn’t a problem. However, if in the next scene they’re in a courthouse and you don’t establish that immediately, they’re going to have one of those “WTF?” moments that throw them out of the story. Do this too often and you’ll have frustrated readers who just might cross you off their favorite author list.
