The phrase "When in Rome, do as the Romans do" is a proverb that means when you are in a different place or culture, you should adapt to their customs and behaviors rather than insisting on your own way.
Meaning:
- It suggests that it’s polite and wise to follow the traditions or practices of the local people when you are visiting or living in a new place.
- It encourages flexibility and respect for cultural differences.
Example:
If you're in a country where it’s customary to remove your shoes before entering someone’s home (like in Japan or many Middle Eastern countries), you should do the same—even if it’s not your usual habit.
Origin:
The saying dates back to the 4th century, when St. Ambrose advised St. Augustine to follow local customs in Rome regarding fasting days, even if they differed from those in his home region.
