Last night while riding my bike in Graças I heard a "panelaço", a common form of protest in Brazil and some other parts of Latin America. A panelaço is the collective banging of pots and pans out windows during a speech broadcasted by unpopular politicians. Luckily I had my handy H2n.
Graças is a wealthy area of Recife and as a result is more likely than others to have citizens who are not happy with the PT (Partido dos Trabalhadores or "Worker's Party") due to recent corruption scandals and general discontent with the leadership of current President Dilma Rousseff.
The panelaço started when ex-president and founder of the PT, Luiz Inácio Lula da Silva (Lula), founder of the PT, came on television. The bangers of pots and pans were out to make as much noise as possible instead of hearing words from someone they considered dishonest and bad for the country.
