Born and raised in France, I just moved to Sao Paulo, after several years spent in the Usa and Canada...
Right now I have the portuguese vocabulary of a 2 years old kid, but I'm working on that! May be we can make a deal: I teach you french (with a parisian accent) if you teach me portuguese...
The good thing is that I have a lot to explore in that city and wouldn't mind having a friendly guide...
