One example - we had a cookie decorating party a decade ago and found once we had a house full of friends that we no cookie cutters at all! I ran to the CVS on the corner and for some reason the only cookie cutters they had were leftover Halloween ghosts… we’ve made Christmas ghost cookies every year since. We wouldn’t dare make trees or wreaths or Santas… our kids think this tradition is passed down for years, with varying insane stories as to why. It’s a huge part of Christmas fun to get out our ghost cutters!
Tradition is the glue of culture.
I will admit that I thought ciabatta was older than 1982, but I do wonder what the perception and presentation of it was like when it did come out in Italy at the time.
Which is why it all has New World plants in it.
In the case of national unity, it seems to have been most effectively implemented by various Chinese dynasties (in fits and starts, of course) and France under Louis XIII and Louis XIV. Famously it was seriously pursued, but luckily not especially effectively, by the Nazi regime.
The case that amuses me most is famous to English speakers, is of course cited in the Wikipedia article: the emergence of a blended "British" culture in the reign of Victoria: Tartans being the most famous, but also national anthems, brides in white, today's formal fashion (suits, military dress uniforms, and the like) and so on. What amuses me most is the ad-hoc nature (so consistent with how the british developed an empire) and especially how widely it spread: North Korean military uniforms look like 19th century upper class dress and Japanese weddings remind one of Victoria's.
You can clearly see leftover pigments, grains of dirt, and various other undertones when you look closely at any museum with these statues. They clearly are nowhere near a pure white colour, without any exception that I've seen.
Of course those folks who don't care enough to pay attention might believe in such a myth, but why try to convince folks that don't care?
No one knows where it comes from, and people with similar backgrounds as me raise a curious eyebrow when its said, but its origin reaches at least as far back as my great-grandmother's generation.
