Really good article from StoryLine about having engaging stories and what a non-engaging story could mean:
All of us play possum from time to time.
We have unique strategies to get people to leave us alone. Some people avoid connection by their humor. Others revert to anger and aggressiveness. Some simply appear uninteresting..
Often, when we walk away from people, while they may be unaware of it, they are acting in some way to repel us. It may be subtle (boredom) or it may be overt (meanness). Sadly, it usually works.
