"Don't you think?"
Translation:Você não acha?
I am sorry... I still don't quite understand. So achar = think as in "Don't you find it so?" As if in response to the comment "This is nice, don't you think?" But if I wanted to ask if your brain is working, I would use "pensa" ? As in the context of "Why would you say something so dumb, don't you think? (Don't you use your head?)... is this right?
