"You're acting like such a bitch."

A few years ago, my mom and I were fighting yet again. As she stormed out of the room, she said, "You're acting like such a bitch." 

I'd never been called something so hateful in my life, not even jokingly. I was too shocked to cry. The person who I loved more than anything thought I was a bitch. 

Now we're best friends and curse each other out occasionally as a joke, but I will never forget that moment.
