2) Don’t Touch Your Food with hands
Say a tray of finger foods is in front of you like hamburgers, pizzas or sandwiches, do not touch it ever with your bare hand as it is considered rude, instead use a napkin to hold. Even if you say your hands are freshly washed, you must follow the procedure.
3) Noise Everywhere
The Brazilians like their noise. Chattering, Singing, honks, whistles, noise – whatever you may call it happens everywhere. Don’t grumble, just enjoy.
The lovers in Brazil show their affection to their partners almost openly. You can regularly see couples kissing and making out on the streets, in schools, on buses and the thing is no one seems to care. It’s a great cultural shock for people from conservative countries.
5) The “thumbs-up.”
The sigh of ‘thumbs up’ may be a universal sign of affirmation; Brazilians use it in many different ways. It can mean anything from “yes,” to “I agree,” to “awesome”.
