If I asked you to describe your best friend to me, what would you say? Would you describe their physical appearance? Maybe their personality? Would you tell me what they did for a living? Would you share what you know about their family (and their family life)? What about their hopes and dreams–and the flip side of that, their losses and disappointments?
Would you be able to tell me what their home looks like and why they chose not only that particular place to live, but why they chose to decorate it–or chose not to decorate it–the way they did? Could you tell me what kind of car they drive, or if they’re afraid to drive, or if they’re environmentally conscious and so only ride a bike or the bus in an effort to shrink their carbon footprint?
Would you share with me how they dress–when they go to work, go out with you, go out with their significant other–or on a first date? How do they spend their downtime? Do they have downtime? How’s their health?
I hope that you know your best friend well enough that you can answer all of these questions and then some.
As your friendly neighborhood editor, I hope that you can also answer every single one of these questions about your main character–and most, if not all, your supporting characters–in your work in progress. If you don’t know your MC and their cast this well, you need to get your rear back to the drawing table.
