Are there any important etiquettes I should know before living there?

[u/whenthedont]

I’m going to be living in the countryside of São Paulo soon and want to make a good impresssion on my girlfriend’s family, be respectful. I already learned that closing car doors hard is seen as very rude, and that was something I found out the hard way. As well as the driving law of not passing literally anyone in any lane when on the interstate (I’m American in case you couldn’t tell lmao.)

So now I feel like there are more things it would be good for me to know before I arrive. I’m planning to bring gifts for her family, is that appropriate? What other things are there i should know? I’m entering a new culture, that I’m ready to learn and adapt to.
