Imagine a friend is talking about a past event that is finished and he has made a decision in the past. While he is talking I want to say that I would make a different decision. How should I say that?
- If I were you, I wouldn't do that.
- If I had been you, I wouldn't have done that.
the first one seems more correct to me. But as far as I know that is often used to talk about the present. What is the right structure to use in these situations?
