[{"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 'Sta' zitto!' is the literal translation of 'Shut up!', it's considered quite rude. A more polite way to express frustration in Italian would be 'Per favore, taci!' which means 'Please, be quiet!' or 'Basta, per favore' which means 'Enough, please'. However, if you still want to use 'Sta' zitto!', please be aware that it's a strong expression and should be used with caution."}]
