The correct translation of 'You saved my life' in Italian is 'Lei mi ha salvato la vita.'"}, {"role": "user", "content": "That's perfect, thank you! I want to make sure I use the formal version since we aren't close friends. Is 'Lei' the formal way to say 'you' in Italian?"}, {"role": "assistant", "content": "Yes, that's correct! 'Lei' is the formal way to say 'you' in Italian, used to show respect or politeness, especially when speaking to someone you don't know well or who is older than you."}, {"role": "user", "content": "I appreciate the clarification. So, if I were to say this to a close friend, would the sentence change?"}, {"role": "assistant", "content": "If you were speaking to a close friend, you would use the informal version of 'you', which is 'tu'. The sentence would then be 'Tu mi hai salvato la vita.' But since you mentioned you want to use the formal version, 'Lei mi ha salvato la vita' is the way to go."}]
