[{"role": "user", "content": "I'm trying to learn Italian to communicate with my friends who are from Italy, and I was wondering how I would express the sentence 'You never showed up' in Italian, could you please help me with the translation?"}, {"role": "assistant", "content": "The translation of 'You never showed up' in Italian is 'Non ti sei mai presentata.' This sentence is in the formal 'you' form, if you want to use the informal 'you' form, the translation would be 'Non ti sei mai presentato' for male friends and 'Non ti sei mai presentata' for female friends."}]
