LMAO! When I first moved to Italy, like you, I only knew a few bad words..lol...It was real tough at first for a 12 year old kid. Even Bugs bunny and John Wayne spoke Italian on TV, how hard could it be?!
My first few months of school were horrible, I was a novelty for the kids...and I was put back 3 years at first to try to learn the language...I am big for an American, 6 ft 3, 350 lbs, at 12 I was already 6 ft tall...enormous for an Italian, I stuck out like a sore thumb....just until the English teacher made the fatal mistake of telling me (in broken English) If I make a mistake, please tell me....remember...I was 12..lol...they were taught the queens English, with words like "rubbers" for erasers, and such...the first time I heard that I nearly fell over laughing..."class, grab your rubbers"....mind you...in Italy, you NEVER spoke back to teacher (professore or professoressa), man, the kids thought I was cool....my very strict Sicilian father....not so much...lol.
But I learned Italian, and the Livornese Dialect so well, you couldn't hear my american accent anymore, but not before making so many embarrassing mistakes, I still cringe thinking about them!
