In the video, the little girl tells the camera that a boy at school told her she looked ugly.
Her response? "I didn't come here to make fashion statement. I came here to learn, not look pretty."
He then apparently told her she looked bad, but she wasn't going to take any more of his snarky comments.
"Did you look in the mirror lately? Buh-bye, see you later...making me mad."
