Cultural Tip
In Brazil, *boa noite* works as both a greeting after sunset and a farewell before bedtime. In Portugal it is slightly more formal and is mainly used as a farewell. The intonation rises a bit when you are greeting someone and falls when you are saying goodbye. Adding a smile or a gentle wave reinforces the friendly tone.
