Brazilian and Portuguese people are known as a friendly and talkative bunch. Knowing how to greet them goes a long way toward helping you make friends. Here are some "hello" and "goodbye" basics:
Tudo bem? (too-doh bang?) (How are you?)
Como vai? (koh-moh vah-ee?) (How are things?)
Tchau! (chah-ooh!) (Bye!)
Até logo! (ah-teh loh-goo!) (See you later!)
Até amanhã! (ah-teh ah-mang-yah!) (See you tomorrow!)
