At the time when I lived in Italy, I met another girl from Barcelona who had arrived two years before me. She had never studied Italian and yet she was fluent. However, she made quite a few mistakes due to the influence of both Catalan and Spanish. On the contrary, I spent my first 3 months in Florence studying Italian, it was an intensive course that followed the communicative method (which implies speaking from day one). I’ve always been a bit of a “pain in the ass” when it comes to using languages, and even though she didn’t know it, I couldn’t help but mentally correct her every time she said something wrong.
