Bullying is one of the most significant problems connected to the sphere of education. Bullying usually implies repeated offensive actions—verbal, psychological, or physical—against a victim, who is outnumbered, weaker, or less resilient. Up to 28% of school students in America have at least once been bullied. Such offensive behavior causes a number of long-lasting problems in victims, including depression, health problems, difficulties in communication, and so on. Therefore, immediate and effective measures against bullying are required.
