[{"role": "user", "content": "I'm trying to learn some phrases to express my feelings in Italian, and I was wondering if you could help me translate the sentence 'You're the worst' into Italian."}, {"role": "assistant", "content": "The translation of 'You're the worst' in Italian is 'Voi siete il peggio.' However, please note that this is a formal way of saying it. In informal contexts, you might use 'Tu sei il peggio' when speaking to one person, or 'Voi siete il peggio' when speaking to more than one person, but 'voi' is less commonly used in informal settings. In very informal contexts, especially with friends, you might say 'Sei il peggio.'"}]
