Talking loudly in a foreign language should also be avoided as it creates a clear barrier between locals and visitors - a sense of 'us' and 'them' - which runs contrary to the philosophy of cultural sharing and learning that should underpin these visits.

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 before going into a visit - such as 'bom dia,' meaning good-day, 'oi,' meaning 'hi,' and most importantly 'obrigado', meaning 'thank you' - a words that should be used whenever possible to show gratitude to the hospitality.

the proper interaction between visitors and residents results in a more rewarding cultural exchange between both groups, and an ever more welcoming and favorable attitude towards favela visits in general.
