I would never beat up a little girl. That is not who I am, that is not what I am about. I would never lay my hand on any woman. My mother raised me better.
However if I am a little girl as well I am 10000% bullying this kid. How the hell is this mom shocked? With a name like ABCDE you'll probably be spending majority of your middle/high school career in a locker.
Watch the Simpsons one time mom and rename your child.
