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 word 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.
