I feel sorry for number 13 and other unlucky things. I think they just want to be ordinary things just like other stuff; or they like it what do I know.
I do think number 13 does have meaning in part because people give it meaning, also through superstition. Also there's the old saying: there are no accidents (and variations of this), and this could possibly be a scientific fact in case we choose to believe in cause and effect.
It feels like there's little meaning to discuss the possibilities of there being any "spirituality"; "mystery"; idk, "mumbo jumbo" in this comment section, the only other thing I want to say is: would your life get richer believing in these things?
