@mcc The moment I knew that I understood english (my second language) was when I was watching a movie with spanish subtitles on and suddenly thought "wait... that's not what they said" and realised that I was both listening in english and reading in spanish. Then I learned that subtitling is way more difficult than it seams because of space constrains and word lengths. Same thing with dubbing and subtitling, they NEVER match, even though they are in the same language.
