Bé, sempre he estat un admirador de la història explicada per en Farid al-Din Attar, sobre un rei que va reunir un grup d'homes savis per crear un anell que li fes feliç quan estigués trist.
Well, you know, I've always been a fan of a story told by Attar of Nishapur, about a king who assembled a group of wise men to create a ring that would make him happy when he was sad.
