[{"role": "user", "content": "Hi, I'm studying Italian for a project about family relationships and I was wondering, how do you say 'Tom needed you' in Italian?"}, {"role": "assistant", "content": "That's a great project! The translation of 'Tom needed you' in Italian is 'Tom aveva bisogno di lei.' If you want to make it more informal, you can use 'Tom aveva bisogno di te' when speaking to someone you're familiar with."}, {"role": "user", "content": "That's really helpful, thank you! So, is 'Tom aveva bisogno di lei' used in formal situations or when referring to someone you don't know well?"}, {"role": "assistant", "content": "Exactly! 'Tom aveva bisogno di lei' is used in formal situations or when referring to someone you don't know well, as it uses the formal form of 'you'.
