Buildings and the 13th floor, or more specifically elavators, as technically the people working/living on what is actually the 13th floor could reject the tyranacil superstition forced upon them by the elavator buttons, and acknowledge it as the 13th floor.
I understand that in some building in the GTA (greater Toronto area) some buildings skip other floor numbers in the elavator etc due to specific cultural superstitions regarding numbers.
It always makes me chuckle inside as if you believe the superstition changing the labels is such a half hearted fake solution, and if you don’t believe, as the fake solution would suggest, why bother ?

Have encountered the salt thing, open umbrella indoors, black cat - - mainstream junk. I honor nothing based on superstition.

Superstitions are for christians. We don't believe in that shit.
