[{"role": "user", "content": "I'm trying to learn some basic phrases in Italian to communicate with my friend who is visiting from Rome, and I was wondering how to say 'You look serious' in Italian."}, {"role": "assistant", "content": "That's great that you're making an effort to communicate with your friend in Italian! The translation of 'You look serious' in Italian is 'Sembri seria' if your friend is a female, or 'Sembri serio' if your friend is a male. However, if you want to use the formal form, you can say 'Sembra seria' for a female or 'Sembra serio' for a male, but the subject 'Lei' or 'Lui' is omitted. So in this case 'Sembra seria' is a correct translation of 'You look serious' when referring to a female."}]
