Idk how Brazilians can be mad or sad. They have tropical weather and beaches all year round and you can be walking down the street and get randomly twerked on.
One third of Brazilians are chuds so they're gonna be miserable no matter what. Another third of Brazilians are socialists so they're always dissatisfied. The last third are quite happy but you don't hear from them because they spend their days robbing the other two and raping stray animals.
