I have an uncomfortable memory of my 1st grade teacher showing this to us and me refusing to go along with what I insisted was an irrational superstition. I didn't understand the context or what her old age meant.
Similarly, I was shocked as a kid when I visited the US and saw apartment buildings skip the 13th floor numbering.

People are weird.
