[{"role": "user", "content": "I'm planning a trip to Italy and I need to know how to express my envy to locals, so could you tell me how to say 'You're so lucky' in Italian?"}, {"role": "assistant", "content": "In Italian, you can say 'Voi siete cos\u00ec fortunati.' to express that someone is lucky. However, it's worth noting that 'voi' is a formal way of saying 'you'. If you want to be more informal, you can say 'Tu sei cos\u00ec fortunato' (for a male) or 'Tu sei cos\u00ec fortunata' (for a female). For a group of people, you can say 'Voi siete cos\u00ec fortunati' (formal) or 'Voi siete cos\u00ec fortunati' (plural informal)."}]
