In the book <em>To Kill a Mockingbird,</em> we meet Aunt Alexandra, Scout's aunt. Scout often clashes with her aunt because of the different ideas that each one of them have about what it means to be a girl.
Aunt Alexandra is very traditional, and she believes that a girl should behave in a lady-like way. This includes wearing dresses, caring about reputation, not playing rough, not climbing trees and playing with dolls. Scout, however, dislikes all of these things and it causes her great frustration to have to deal with the ideas of her aunt.
If im on the right track then a way to right it with dashes would be: Sacrificing her was a mistake-a mistake that could have been avoided. but i may not have understood the question??
