That’s quite the interesting tidbits.
These types of superstitions do make me roll on the ground. That 13 number, like on building’s elevators when they skip it, where buttons go from floor 12 to 14... are people really unaware that no matter what it says (that button could have a sticker that says floor 418) physically it is a 13th floor.
How do people deal with that! Scary! /s
