This past year, like Alice, I went down the rabbit hole. No Queen of Hearts in my story, but a Miss Potato Nose. She also yelled, "Off with their heads", at the top of her lungs, while she swung her machete around and changed the life of all of those about her.
I have read and reread the book by Martha Stout: The Sociopath Next Door. I had read it prior to having my head cut off and still could do nothing when it happened because we want to believe that those whom we like cannot be so heartless.
Only now am I getting round to it, and I have acquired a nice new potato-peeler.
