I will never go to this class again after the stunt I pulled today. I was half asleep, then it was my turn to say something in French. I did my attempt of perfect Spanish-French, was half asleep while doing so, said something wrong, didn't understand what I did wrong and said to the teacher: "Qué querés, man?!".
At least I know now that I'm fluent enough in Spanish to make stupid comments while being half asleep. Oh my.
