^^ I love that idea, Maurice.
Years ago, I did something similar for a project I was working on with a friend. My friend was dissatisfied however with the development of two characters - a couple - in the story. So I spent a weekend writing just a blurb about these two, what their daily life was like, their routine, their breakfast conversation with the Sunday paper, etc. to illustrate everything else we'd already sort of devised for the couple in the actual short film we were ramping up to produce.
Those breakfast scenes never made it into the film, but they were hugely informative for the characters as we continued writing and for the actors when we were filming. And while Sunday breakfast might not be the most exciting or original of scenes, for our purposes it worked quite nicely.
