INFORMAL GREETINGS - Good morning, good afternoon, good evening. Saying good bye: Good night, bye, see you later/soon, so long, take care, see you around. FORMAL GREETINGS - How are you? How are you doing? How are things with you? How are things? How's life treating you? (Traduzindo tudo= COMO VOCÊ ESTÁ?) I'm sorry but I have to go now (Desculpa, mas eu tenho que ir)
