I can’t remember the exact age this happens--probably 3 or 4--but at some point we all become aware of our nakedness. It’s no longer all right to run around the house in our birthday suits. Mom and Dad aren’t allowed to give us a bath anymore. In our civilized world, we learn at a very young age to cover ourselves.
What does this have to do with writing fiction?
How much of yourself are you willing to show? Do your feelings about life, death, love, hate, jealousy, indifference, rage, honesty, courage, etc. end up on the page? How much of yourself do you put in you characters?
Do you hold back a bit, covering your naked soul with at least a fig leaf, or do you let it all hang out? Are you embarrassed for people to “see” you?
Or, can you dance like nobody’s watching?
