if … were in …'s position
もし私があなたと同じ立場だったら、今夜は早く寝ると思う。
If I were in your position, I think I’d go to bed early tonight.
もし私が君の立場だったら、そうはしないだろう。
If I were in your shoes, I wouldn't do that.
私があなたの立場だったら、辞めているだろうに。
If I were you, I'd have quit already.
君が僕の立場だったら、どうするかね。
If you were in my shoes, what would you do?
もし君がその立場だったら許可するか?
If you were in that position, would you allow it?
— 善き人のためのソナタ (2006)
君が僕の立場だったら、どうしたか考えてほしい。
I want you to think about what you would have done if you were in my position.
君の立場だったら、私も同じ事をするだろう。
If I were in your position, I would do the same thing.
