Some characters understand their role.
They arrive.
Say what the story needs them to say.
Perhaps serve coffee.
Then they leave.
I appreciate these characters.
They are professionals.
Others are more difficult.
They appear in a scene with one purpose and immediately begin behaving as if they have signed a long-term contract.
The person behind the counter remembers something.
The journalist asks one question too many.
A quiet man in an office has a history I did not request.
Suddenly, I am taking notes.
This is how trouble begins.
A story has limited space.
Every character added to it changes the balance.
Names require memory.
History requires explanation.
Relationships create consequences.
The sensible response is often to simplify.
Thank the character for their contribution.
Remove the unnecessary paragraph.
Continue with the people who were actually invited.
I have done this.
Occasionally, it even works.
But sometimes a character refuses to become unnecessary.
They remain in the back of my mind after the scene is finished.
I begin wondering what they do when the main characters leave.
Who closes the café?
Where does the journalist keep his files?
Why did the old man pause before answering?
These are dangerous questions.
Not because every answer belongs in the book.
Most do not.
They are dangerous because curiosity is expensive.
One question becomes a page of notes.
The page becomes a history.
The history creates another person.
That person, naturally, refuses to leave.
There is probably a lesson here about discipline.
I intend to learn it eventually.
For now, I have developed a different rule.
If a character remains interesting after their purpose in the story is complete, I do not immediately give them more pages.
I wait.
Time is useful.
Some characters disappear when ignored.
Others become louder.
The loud ones are rarely actually loud.
They simply keep leaving small questions behind.
A name.
An old photograph.
A folder nobody has opened.
A twenty-five-year absence that begins to look suspiciously large when written down.
At some point, the writer has to admit what has happened.
The character was not refusing to leave.
The room was simply larger than expected.
This is inconvenient.
There are already enough books to write.
Apparently, the characters have not been informed.
