But any challenge to the social order is met with punishment. The parents are distracted, emotionally wrapped up in themselves. The kids are all eachother has, but that doesn’t make them friends. A single moment between the two sisters almost changes everything and Mathilda is forced to be brave in the face of emotions she doesn’t understand.
