Important Notes:
* Brazilians tend to be very friendly and outgoing, so don't be afraid to greet people even if you don't know them well.
* When greeting someone for the first time, it's polite to shake their hand.
* It's also common to give a hug or a kiss on the cheek to friends and family members.
Bonus Tip:
* Learning a few basic Portuguese phrases, even just "Olá," "Obrigado/Obrigada" (thank you), and "Por favor" (please), will go a long way in showing that you're making an effort to communicate with locals.
