A southern Alberta city got a little brighter today after hundreds of neon Post-it notes with inspiring hand-written messages started popping up at homes, shops and offices in Airdrie. The movement was started by a local high school student trying to fight off a bully. Caitlin Prater-Haacke had been sent a message on Facebook telling her to kill herself. Instead of replying to the message, Prater-Haacke took out a marker and some small pads of paper. She decided to fight back by posting positive messages on every locker in her school. Little simple messages like, 'You're beautiful' [and] 'You shine bright like a diamond,'" she said. But officials at George McDougall High School didn't like the idea and told her it was littering, which didn't sit well with the community. City council then declared Oct. 9 as Positive Post-it Day. "What's come out of it is 100 times better," said Prater-Haacke, adding she can't believe the support she has received. The school is now filled with the sticky notes, and this time the school says the colourful messages can stay. But it wasn't just among students, as other Airdrie residents also embraced the movement. "I think it put a smile on everyone's face this morning and I think it gave them that little bit of extra oomph for the morning to get them going," said resident David Jones. The campaign has taken off online.
