The translation of 'I'm sorry I lied' in Italian is 'Mi dispiace di aver mentito.'"}, {"role": "user", "content": "Grazie! I really appreciate it. Can you break it down for me so I understand it better?"}, {"role": "assistant", "content": "The phrase 'Mi dispiace' means 'I'm sorry', 'di' is a preposition that means 'of' or 'about', 'aver' is the infinitive form of the verb 'to have', and'mentito' is the past participle of the verb'mentire', which means 'to lie'. So, 'Mi dispiace di aver mentito' is a way of saying you're sorry for lying."}, {"role": "user", "content": "That's really helpful, thank you! What's the difference between 'Mi dispiace' and 'Scusa'?"}, {"role": "assistant", "content": "'Mi dispiace' is a more formal way of saying 'I'm sorry', while 'Scusa' is more informal. You can use 'Scusa' with friends or in casual situations, but 'Mi dispiace' is better suited for formal situations or when you want to apologize for something more serious."}]
