it's a tough one for me.
I always wanted to learn italian, and I think italian is a beautiful language, so if I was born in italy, well, there we go, I have my wish, plus I am in the home of pizza- literally the best food ever
I listen to a lot of spanish music, so spain would be a close second
and my best friends (or most of them), live in the US, and let's face it, days out at disney/ universal/ seaworld would be pretty fun
