The translation of 'I forgot them' in Italian is 'Io mi sono dimenticato di loro'.

What's the difference between the formal and informal way?"}, {"role": "assistant", "content": "In Italian, the formal way is used when you're speaking to someone you don't know well, or someone who is older or in a position of authority. The informal way is used with friends, family, or people you're familiar with. So, 'Io mi sono dimenticato di loro' is a bit more formal, while 'Mi sono dimenticato di loro' is more informal."}, {"role": "user", "content": "That makes sense. Can you give me an example of when I would use the formal version?"}, {"role": "assistant", "content": "For example, if you're speaking to a teacher or a boss, you would use the formal version: 'Io mi sono dimenticato di loro'. But if you're speaking to a friend or classmate, you can use the informal version: 'Mi sono dimenticato di loro'."}]
