[{"role": "user", "content": "I'm trying to improve my Italian skills and I came across the phrase 'I saw what you did' - could you please help me translate it into Italian so I can understand its meaning and usage in context?"}, {"role": "assistant", "content": "The phrase 'I saw what you did' can be translated into Italian as 'Ho visto cos'hai fatto.' This phrase is often used to imply that someone has witnessed another person doing something, usually something they shouldn't have been doing, and is now confronting them about it. It's a bit of an accusatory phrase, so use it in context accordingly."}]
