talking loudly in a foreign language should also be avoided as it creates a clear barrier between locals and visitors, such as a sense of 'us' and 'them' - this runs contrary to the philosophy of cultural sharing and learning.

understanding a bit about carioca culture in general is advised - for instance, soccer is very important in rio de janeiro, thus avoiding wearing t-shirts of adversaries soccer teams is always appreciated and a polite gesture.

ideally, visitors should learn a few basic words in portuguese before going into a visit - such as 'bom dia,' meaning good-day, 'oi,' meaning 'hi,' and most importantly 'obrigado (men) and obrigada (women)', meaning 'thank you' - these words should be used whenever possible to show gratitude to the hospitality.
