Maybe it's just me, but when I get into a big anime kick or watch a movie with a lot of foreign languages or accents, my little head-voice starts to talk just like that too... Like, I'll be using little Japanese phrases, or talking in a British or Spanish accent. I'm not a super-big language buff or anything, but I apparently have a knack for picking up accents and pronunciation habits from other languages. Does this kinda thing happen to anyone else? Just curious :)
