So I did what any one would do! I Cut it so it was even and so it looked fine.
I think I was so sick that I wanted to cry. Katelynn at first was very proud of her self. Then trying not to hurt her feelings I said she needs to come to me if she wants to do something like this and always ask for scissors. I made her take a look in the mirror and told her we have to even it out and that she's going to have short hair. She was so sad that she said her good byes and told her hair she will miss it. For her birthday she got a Rapunzel barbie which came with scissors that are plastic and fake. They allow you to cut her hair that can be placed back on after cutting. For some reason I think this put false thoughts in to her head.
She said she has learned her lesson!
