So today in Italian (our second day) we learned how to say what month we were born, and the teacher started going around and he asked me, "Lei in che mese e' nata?" and I replied automatically, "Io sono nato in mazzo." He corrected me to "nata". It stung. Fortunately, I said something to him after class and he said it's ok for me to use the masculine to refer to myself. I'm so happy. ^_^
