Non-native Portuguese speaker situations we can learn from I've just seen this awesome video, on Small Advantages Youtube channel, about mistakes of a non-native Portuguese speaker. Link: https://www.youtube.com/watch?v=EdSnfouTTlE I think sharing what I've seen will serve two purposes: helping me practing English writing and Portuguese non-natives speakers a bit about what not to do (in a funny way) when talking to brazilians. Gavin Roy had been traveling across many cities in Brazil. He shares his experiences through his Youtube channel and talks about cultural differences, what he enjoys, finds weird, and so on. One of his last videos I've seen was about some (in his words) ridiculous mistakes he'd done when learning Portuguese. I'll describe one of them. When he arrived in São Paulo, he struggled to understand why cashiers greeted him with "Good morning/Good afternoon. CPF?" (in Portuguese, "Bom dia/Boa tarde. CPF?"). So, he thought this was a common addition when greeting. So he kept saying that for people he met, which provoked laughs. But it happens it's just that here, at stores, people asks for a personal identification number (CPF stands for "Cadastro de Pessoa Física") when generating invoices (put it on the invoices). That enables us to retrieve, later, part of the taxes payed, since it helps the local government controlling/supervising tax payments. There are other amusing mistakes he did that everyone could learn from. By doing and sharing it with us, I guess he had fun and learned a lot from it.
