What kinds of things you don't need to take too seriously in Brazil
Since I've moved here I met a lot of new people and now I can understand better the Brazilian way to deal with friends and people whom they like.
Brazilians are really open, friendly and helpful people but not compromised at all.
Maybe you've already heard about their punctuality. They never come at the scheduled time and it doesn't matter if we talk about job interview or friends appointment, party, etc.
If you want to invite any Brazilian for a dinner and is planning to start it at 6, so ask a person to come at 5.
This one is a famous cultural peculiarity but there is another one which used to make me really upset during the first year here.
People here like very much to invite you for any activity, for example, "Let's go to the cinema this weekend", or "Let's make a barbecue next week at my place", "Let's to go the shopping together tomorrow" and so on, but the truth is that it means nothing. It's just a kind way to show you that they like you and want to see you again someday. It doesn't flash through their mind that you can take it seriously.
At first, I couldn't understand it. If someone invited me to go some place at the weekend I would be waiting for it to happen. It took me a long time to get used to accept it, but now I can totally deal with it and don't believe anymore in this kind of invitations except the person confirmed the appointment twice.
