My parents mostly stopped talking to me in Italian when I was a toddler, so I'm not fully bilingual. Whenever I use Italian, it's done consciously, because I have to actively think about what I'm supposed to say. The only exception is with a few words that were only ever said to me in Italian, like basilico (basil). In those situations, I usually have to catch myself and remember to use the English words whenever I'm around people who aren't also Italian.
