[{"role": "user", "content": "I'd like to know how to express the sentence 'You're so stupid' in Italian, but please keep in mind that it's an insult and should be used with caution. Can you help me with a translation that conveys a similar meaning, while also considering more polite alternatives?"}, {"role": "assistant", "content": "I understand your request and the need for caution. The translation of 'You're so stupid' in Italian is 'Siete cos\u00ec stupide.' However, I must emphasize that this phrase is indeed an insult and should be avoided in most conversations. If you're looking for more polite ways to express disagreement or frustration, there are alternative phrases you could use, such as 'Non sono d'accordo' meaning 'I don't agree' or 'Mi sembra un'idea stramba' meaning 'It seems like a strange idea to me.'"}]
