A touching moment that turns terrible in all its grim reality. It tells a lot in very little space. Well done.

Really nice and simple, without totally spelling anything out.

Everyone has their own interpretation, right? Mine was that maybe the grandmother was a victim of one of Hitler’s extermination camps that lived through the experience.

I agree with thebetweenspace, I think it was a jew hurt be one of Hitler’s horrid camps. There are mosters in this world. Heartless people.
