Lessee...bilingual, trilingual, quadrilingual...
I was raised bilingual (my father is Italian and my mother is Austrian). I grew up in Switzerland where French, English and proper German are mandatory school subject. Because my father is from a hillbilly-area of Italy and only spoke in this dialect to me I picked it up. This dialect is to Italian what Brad Pitt's gibberish in Snatch is to English. You might understand a word here and there but you have to pay close attention.
I'm aroused.
This story arouses you? That's not good.
