I am going to change the way I was looking at this. As I watched I wondered if she is just a little spitfire who does things her own way rather than a being bit delayed. Jana wasn't pleased because it wasn't nice and pretty like the other quieter girls. Perhaps Josie has a different idea about art? Really in art there is no right or wrong. I heard her say she was laying it on thick because she wanted ridges. Then I flashed to a scene where Josie and others were playing outside maybe around trees (my memory of the background is hazy) and she did what looked like joking around with a stabbing motion and a silly face. I saw that as a funny and perhaps zany sense of humor. I can see 'different' wouldn't be tolerated. Maybe she is the Picasso to their Thomas Kincade? I didn't really like her being told to leave and being reprimanded, about art. A personal thing. Maybe in Josie's head she is thinking fuck this, I want to go play the drums or something.
