[{"role": "user", "content": "I'm trying to learn Italian to better communicate with my friend who's from Italy, and I was wondering, how would you translate the sentence 'You're unreliable' into Italian?"}, {"role": "assistant", "content": "The translation of 'You're unreliable' into Italian is 'Lei \u00e8 inaffidabile.' This sentence is a formal way to express that someone is not reliable. If you want to use an informal tone, you can say 'Tu sei inaffidabile', but 'Lei \u00e8 inaffidabile' is more polite and suitable for most conversations."}]
