Since I've been in an actor, I've lived in Italy, in London, in Stockholm - I had the fortune of working in different locations. If you live someplace long enough, you acquire slightly different systems of thought, and it influences your outlook on life. I just slowly adapted the way I speak.
When I was young, an eccentric uncle decided to teach me how to lie. Not, he explained, because he wanted me to lie, but because he thought I should know how it's done so I would recognise when I was being lied to.
