Cultural Tip
In Brazil, saying ‘Boa noite’ is customary not only when you’re about to sleep but also as a polite farewell after dinner parties or any evening gathering. Unlike some languages, you don’t need to add a verb; the phrase alone is sufficient. In more formal settings, you might say ‘Boa noite, senhor/senhora’ to show respect.
