Caitlin Prater-Haacke of Alberta, Canada was urged by bullies to kill herself, via Facebook post. Instead of sinking into negativity she turned the situation into a positive lesson. Lee Hirsch, director of the documentary Bully," which aired Monday on PBS Monday, is among those lending their support to Caitlin, who was reprimanded by her school for her "Positive Post-It Day" approach to bullies. In late September, someone broke into Caitlin's locker at George McDougall High School in Airdrie, a community just north of Calgary, and wrote a Facebook status using Caitlin's iPad that encouraged her to die. Rather than letting the bully win, the 11th grader wrote inspiring, positive, encouraging messages on 800 Post-It notes and left them around her school - with messages like "You're beautiful," "Love yourself," and "You're awesome." Now her campaign has also taken to Twitter with the tag #PositivePostItDay. "Bullying is not necessarily addressed, and people get really down about it, I wanted to do something positive - it was about due time," Caitlin told the Toronto Sun. Caitlin's town, led by a mayoral proclamation, banded together to launch a new anti-bullying campaign called "Positive Post-it Day" which encourages residents to leave anonymous notes of kindness for one another each year on Oct. 9. "What I really got out of this story is the way this student chose not to be derailed by this negative experience," said Hirsch. "She became a role model to her classmates, teachers, her mayor and her town."
