Me: We should write!
Brain: Okay! But wait! We need to figure out the background for this character first and their relationships with other people.
Me: That's not important since we don't meet those people until later in the story.
Brain: No. We need to know NOW.
Me: We don't.
Brain: We do.
Me: Let's just write!
Brain: As soon as you figure out whether or not this character actually even knows these background people that may come into the story later on.
Me: Ahhhhh!!!!! *bangs head on table*
