text_A: My dear friend, please forgive me, if I can’t pay you a visit, but since I found someone to carry a message, I’m sending you news on this tape. Here we play football, there’s lots of samba, lots of choro and rock’n'roll. Some days it rains, some days it’s sunny but I want to tell you that things here are pretty dark. Here, we’re wheeling and dealing for survival, and we’re only surviving because we’re stubborn. And nobody’s drinking because without cachaça, most survive this squeeze.
text_B: Is drinking cachaça a good idea, according to the author?
NO.
