내 입장이라면 in my shoes

A : I don't think it's anything to get upset about.
     그렇게 흥분할 필요가 없을 것 같은데.
     Just stop doing business with people like that. 
     그런 사람과는 거래를 끊으면 되잖아.
     It's pure and simple, isn't it? 
     간단한 거 아냐?

B : You wouldn't be saying that if you were in my shoes.
     너도 내 입장이라면 그렇게 쉽게 말할 순 없을걸.
