So, if you're speaking to someone you don't know well, or someone who is older or in a position of authority, you would use'sua'. But with friends or people you're familiar with, you can use 'tua'."}, {"role": "user", "content": "That makes sense.

If you're in a formal workplace or don't know them well, 'Com'\u00e8 stata la sua giornata?' is a good choice.
