Fifteen-year-old Maisie Kate Miller has been picked on by bullies before, and she didn't let it get to her. But when a tormenter at school made fun of her hairdo, it was the last straw -- and Maisie wasn't going to stand for the insults anymore.

Boston-area teen, Maisie Kate Miller, without her pigtails

According to Today, the Massachusetts teen was mocked for her hairstyle by a girl bully, said to her: “Who wears pigtails still? What is this, kindergarten?” Maisie had been picked on for her clothes, boyfriend and body, but being mocked for her favorite hairstyle was a first.

“I turned around and she said, ‘Keep walking!’ I don’t know, I was having a hard week anyway, and by the time I got to bio, I was crying," Maisie told the Washington Post.

Although she cried through her next class, Maisie didn't dwell in her anger for long. She decided to stand up to her bully by wearing pigtails to school all week and encouraging her friends to do the same. She created a Facebook page urging others to join her effort. Clearly, she had hit a nerve: Hundreds of classmates responded within hours and showed up to school the next day wearing pigtails.
