Script (guión): Idioms. I'm doing two together here as they are related. ‘In the red and in the black’. If your bank account is in the red it means you are overdrawn. If it is in the black then you are in credit. I'm currently in the red at the moment actually so if any of you guys could donate any money to the idiom explanation fund. Details are at the bottom of the page. Thank you very much.
