I'm not particularly superstitious. I step on cracks willy-nilly, I spill salt without tossing it over my shoulder, and I pay no attention to cats of any color.
My mother used to have some sort of thing that you needed to exit the house by the same door you entered, or vice versa. I don't remember. My grandmother thought the weather had been messed up by the astronauts going to the moon. She also thought that if it rained while the sun was shining, then it would rain again tomorrow. She obviously didn't live in Arizona.
This is a drawing I did on a book from the American Lending Library. It has no real relation to superstition unless you are a librarian, in which case you may believe that people who draw in library books go to hell.
Or at least deserve to.
