"Your hair doesn't look THAT bad today."
/Growing up, I was picked on constantly, but most of the kids who bullied me eventually stopped by middle/high school. Except for one girl in particular. She was the band director's stepdaughter, basically making it impossible for me to do anything about it.
I'll never forget the day when we got our pictures taken in our marching band uniforms. I had just gotten my hair cut and highlighted the day before, and thought I looked really pretty.
She walked up to me and said, "Oh, your hair doesn't look THAT bad today."
I felt like someone had kicked me in the stomach.
