1. A buenas horas, mangas verdes (“It’s too late, green sleeves.”)
Don’t try to find any hidden meanings added by the mysterious green sleeves part. We could just say “a buenas horas” (“it’s too late”), but everyone would understand, and we wouldn’t be able to confuse non native speakers. In case you’re curious, the green sleeves refer to the Santa Hermandad, a group of soldiers in the Middle Ages, whose uniform had green sleeves, and who, apparently, arrived too late often enough to inspire a popular saying.
