While in Rio, I've tried not to photograph people without their consent. What a mistake, obviously! :)) With few exceptions, I ended up photographing mainly street performers, who seemed to be glad about it and to whom I gave a few coins in the end. There was a cook in the Corcovado restaurant that just kept laughing, when we asked him something in our European Portuguese. Basically, he couldn't understand a word of what we said!. For decades, we've been exposed to the Brazilian media (soap series, talk shows, etc) in Portugal and we can now understand their accent quite well. Sadly, the opposite doesn't happen yet.
