From 8-year old Hilda’s diary:

I haven’t written in this book for three weeks because I have been sick, but I don’t remember getting sick. It was after seeing the moving picture. They told me that I woke up in the middle of the night screaming and talking about knives and crowds of angry people and drums and blood. Grandmother had to call the doctor to give me something to make me stop screaming. But now I am glad I was sick because Sancha is gone. They know all about the butcher shop and the moving picture and I am not going to have a nurse again until Alma comes back.
