Quem já leu Augusto dos Anjos sabe q esse estereótipo dos brasileiros como um bando de bobos alegres q tão sempre festejando e contentes é falso, sempre existiu esse lado melancólico, amargo, cínico e excessivamente autoconsciente no brasileiro
This is how Augustin de Saint-Hilaire, French botanist and traveler, described Brazilians in 1820:
"What seems certain is that everything took place in an orderly fashion, without the shedding of a single drop of blood. This people carry out revolutions with a wisdom that I never tire of admiring, though its causes are easily understood. Brazilians are naturally cold, slow, and not very passionate; since I have been in this country, I have not yet met a single person who displayed any enthusiasm. Even the children have surprised me with their grave and reflective demeanor—they are men in miniature. With this character and accustomed to blind submission, this people must naturally continue to maintain respect for authority, even when revolting against it."
The hypersocial, extroverted, loud, obnoxious, criminally-inclined Brazilians people think of because of the media and the internet are a tiny subset of specifically Cariocas (people from Rio de Janeiro) and university students.
To think all Brazilians are like this is to say "Americans wear large gold chains and play basketball all day" without asking "which Americans?"
