I just want to know how the brain is so capable of sorting the languages into different "angles" as you put them. That you can never get confused between the two languages, not a single word out of place. I can be pretty scatterbrained sometimes and get confused with things and I forget a LOT of stuff. But if I hear a word in another language I know, I never confuse it for English. Heck sometimes I can even hear a word from another language I don't know but somehow it still FEELS like a word from that language.
