Moonlighting as a ghost writer

Mimi is writing Luca's novel. 
Following his disappointment with acting (last week, in a TV studio, with the rest of his class; it wasn't directed by him; he hated it) he is turning his dictatorial aspirations to the world of publishing. 
He is extremely bossy. 
Throws a few rehashed high level concepts around the place, convinced that he is creating something groundbreaking. 
Has zero tolerance for feedback. Changes his mind every 12 nanoseconds. 

I am quite sure that he will be a Lean Sick Sigma black belt some day. 

Mimi on the other hand is writing the novel that she wants to write. While letting him think that he is in the driving seat. 

I am quite sure that Mimi will have a real job some day. 

As you can see here, I witnessed a strange optical phenomenon in the back garden. Some unusual instances of localised darkness.

The scientific term for them is “shadows”.
