What did Atticus mean when he said, “You children last night made Walter Cunningham stand in my shoes for a minute. That was enough To kill a mockingbird?

Atticus means that Scout helped Walter Cunningham realize that Atticus was just a person.

Atticus does his best to try to teach Scout empathy. He tells her that she will get along with a person better if she is able to “climb into his skin and walk around in it” (Chapter 3) Scout learns this lesson well. When Atticus’s client is threatened because he is a black man accused of raping a white woman, he decides to sit outside the jail in case anyone comes. Scout and Jem see what he is doing and go to see what is going on.

Walter Cunningham and his gang do come for Tom Robinson. However, Scout walks up to Walter and begins talking to him.
