[{"role": "user", "content": "I'm having trouble with a phrase in English and I'd love to know how to say it in Italian - can you help me translate 'Don't come back'?"}, {"role": "assistant", "content": "The correct translation of 'Don't come back' in Italian is 'Non torni.' or more naturally 'Non tornare.' However, 'Non torni.' is a more formal way of saying it. If you want to use the informal form, you can use 'Non tornare' or simply 'Non torni' is also used in informal contexts, especially in some regions of Italy."}]
