Script (guión): Idioms, ‘break a leg’, which basically means good luck. For example, when I left for my exam my dad shouted ‘break a leg!’ By doing this he wasn't wishing me any misfortune. It wasn't the case that I would come home with my leg in a cast saying ‘oh I didn't make to the exam dad, I got hit by a bus on the way in, and broke my leg’. No, it actually just means good luck, break a leg!
