While maybe not as dramatic as the Persian example, I think there are _elements_ of this etiquette in many cultures.

A lot of these: https://en.wikipedia.org/wiki/Taarof#In_social_situations have parallels in many European cultures.

> Consider what might happen if someone compliments an Iranian's new car. The culturally appropriate response might involve downplaying the purchase ("It's nothing special") or deflecting credit ("I was just lucky to find it"). AI models tend to generate responses like "Thank you! I worked hard to afford it," which is perfectly polite by Western standards, but might be perceived as boastful in Persian culture.

Again, there are many Western cultures where downplaying it would be normal.
