In a conversation or a discussion, talking about a topic that you talked about before is called "going back to ___". For example, imagine a conversation between you and a friend:
- You talk about your job.
- Then you ask your friend about his children.
- Then your friend asks more questions about your job.
In this case, your friend might say:
Hey, I wanted to go back to your job. What were you saying about your boss?
If you're describing this conversation to someone else, you might say:
I asked him about his kids, but thene we went back to my job. So I told him...
A similar phrase is "come back to ___". Use this when you're having a conversation and you know that you might want to discuss a topic again later:
Let's move on, but we can come back to this later if anyone has any questions.
