I just read an article online and thought "this is great, I should forward the link to Phoebe."
Phoebe is one of my characters.
I've already had characters tell me how they would speak or dress, what their underlying motivations are, or who they are when they grow up (the main action takes place when they're teens/pre-teens in 1995, so they're in their 30's now).
In some ways, that's similar to the question Characters that take on a life of their own. But that's still within the story.
Now my characters are jumping out of the story and worming their way into my life. What's the best way to channel, handle, or survive this part of the writing process?
