[{"role": "user", "content": "I'm looking for a phrase to express frustration, but I don't want to be rude when I'm in Italy. How do you say \"Shut up!\" in Italian?"}, {"role": "assistant", "content": "While 'Stai zitto!' is a direct translation of 'Shut up!', it's considered quite rude. A more polite way to express frustration in Italian would be 'Per favore, silenzio!' or 'Pu\u00f2 per favore stare zitto?' which means 'Please be quiet.' However, if you still want to use 'Stai zitto!', be aware that it's informal and may offend some people."}]
