Pink Against Bullying In 2007, a boy in Nova Scotia, Canada, wore a pink polo shirt on his first day of high school. According to students, bullies threatened the boy because of his shirt color. Two seniors, David Shepherd and Travis Price, were disturbed by the bullying and came up with an innovative response. They emailed classmates, explaining the situation and suggesting that everyone wear pink the next day. They also bought fifty pink shirts to distribute at school. When the boy who had been threatened arrived for his second day of high school, he was met by hundreds of his fellow students wearing pink. The action served as a clear anti-bullying message. The news of the event quickly spread to other schools, many of which instituted their own "Pink Shirt Days."
