Hysterical amnesia--or is that "historical"

I have to tell you this story...

A young girl read Whale Song a couple of years ago and decided to use it for her school book report. She made the most beautiful collage, with pictures and layers. There were blocks of text describing parts of the story.

In Whale Song, the main character experiences a traumatic event that left her with hysterical amnesia. Hysterical amnesia occurs after traumatic events and is short term memory loss related to that event.

Throughout the collage, this young fan called it "historical" amnesia.

I thought this was hysterical. LOL
