[[{"role": "user", "content": "I'm planning a trip to Italy and I'd like to be more polite when interacting with locals, can you help me translate the sentence 'I didn't see you' into Italian?"}, {"role": "assistant", "content": "Of course, I'd be happy to help you with that! The correct translation of 'I didn't see you' in Italian is 'Non vi avevo visti.' However, please note that this is a formal way of speaking.
