There is also 'A Hora da Estrela' by Clarice Lispector. This story delves deep into the life of a simple and ordinary woman, showing her hopes, dreams, and the harsh reality she faces in a very poignant way.
Sure. 'The Third Bank of the River' by João Guimarães Rosa is a great one. It's a rather mysterious story about a man who decides to live on a boat in the middle of the river, distancing himself from his family.
Another interesting short story is 'Macunaíma' by Mário de Andrade. It's a complex and rich story that combines elements of Brazilian folklore and modernist literature, presenting a unique view of Brazilian society.
