National Day For Fight Against the Aggression in School

Every year on the last Wednesday of February, "Pink T-Shirt Day" takes place in Bulgaria, reported the Bulgarian National Television. Here, what's the story: 

The initiative dates back to 2007 when two boys in Canada stood behind a friend and classmate who was bullied because he came to a school with a pink shirt.

The next day the boys bought pink t-shirts and gave them to everyone in the school who have the courage to wear them.
