Original in Spanish: Siempre se ha hecho así

Hello hive mind,

I’m looking for examples of stories that have to do with “it’s always been done this way”.

The one about the monkeys showered with water and the ladder won’t do, because I want something that actually happened.

The puerperal fever one would work, but I’d rather have a different story. Can anyone think of one?
