My Fiction Writing teacher, after critiquing my story* the other day, noted that I have the tendency to switch POV. Let's take this brief sketch I just wrote up: Mr. Joshua Hughes sat down in the far corner of the mess hall of his ship. Next to him was one of the younger ship doctors. "I trust your evening went well?" he asked. The ship doctor looked at him with a weak smile. See? How do I know if I'm accidentally switching perspective? My teacher always tell us to imagine our protagonist walking around with a camera strapped to his/her head and to describe what he/she is seeing. * We all write our own story scene and have the class go over it.
