[{"role": "user", "content": "I've noticed people saying 'You've changed' a lot when they're upset or concerned about someone. Can you help me translate that phrase into Italian, so I can understand it better in different contexts?"}, {"role": "assistant", "content": "The phrase 'You've changed' can indeed carry a range of emotions depending on the context. The correct translation in Italian is 'Siete cambiati.' However, it's worth noting that 'Siete cambiati' is the formal or plural form. If you're speaking to a single person you know well, you would use 'Sei cambiato' (for a male) or 'Sei cambiata' (for a female)."}]
