Sim e Não(Yes and No) is the fifth album released by Brazilian band Nando Reis e os Infernais. Two songs from the album were inspired by people close to Nando Reis: "Sim e Não" (inspired by his ex-girlfriend Nani) and "Espatódea" (inspired by his daughter Zoe). Commenting on the latter, Reis said once Zoe asked him when he would compose "O mundo é bão, Zoézinha"(lit. The world is good (spelled as it is normally pronounced in the hillbilly dialect), Little Zoe, in a reference to the song "O Mundo É Bão, Sebastião!", which Reis had written for his son Sebastião). "I tried to postpone it, but she didn't fell for that. Then I did this song ("Espatódea"). Unlike my other children, there is a particularity in our case: she's red-haired. And the son touches this bond of ours. "Espatodea" is a tree that has an orange flower. Zoé's hair has an intense orange color because she's very white."
Sim e Não marks the first time Reis did not songwrite under the influence of alcohol and other drugs. He remarked this by saying:
It wan't easy. I was always seen as an artist linked to drugs and alcohol and that wasn't for nothing. I had this as a stimulant for my creative process. For a while, it had its benefits. But, with all that dependence and addiction, it started to be bad.
