Sometimes a work is inspired by a title, sometimes a title is inspired by the work.
In this case the work was inspired by the title, and the title was inspired by lyrics from the song called “Bliss” by Tori Amos:
I always wondered what she means by the words: “Father, I killed my monkey”?
To me the monkey represents curiosity and playfulness, so maybe that’s what I’m killing when I am too serious sometimes.
