    School is a difficult time for both teenagers and their parents. For adults, it is the time when they worry about how their child (or children) succeeds in studying, socializing, and what habits and manners a child adopts from peers. For children and teenagers, school is difficult not j u st because of having to study and to try to receive good grades, but also because there is a specific hierarchic environment they have to fit into. Those who cannot do so often become victims of bullying.

    Although some people tend to see bullying as any conflict or act of violence occurring between students, it is not so. For instance, if two students involved in conflict are of approximately the same physical or psychological strength, the quarrel between them is not considered bullying. Bullying has two main components: repeated physical, verbal, or psychological harmful acts, and imbalance power. Bullying includes assault, intimidation, spreading rumors, pressing for money, destruction or theft of property, name-calling, and so on. In the United States, bullying can also include sexual harassment and ostracism based on sexual orientation.

    Surveys disclose that name calling as the most prevalent type of bullying; next goes teasing, rumor-spreading, physical incidents, purposeful isolation, threats, belongings being stolen and sexual harassment. Researchers believe that considering the scale of the problem, it is not enough to just promote a message like "Bullying is not tolerated"; instead, there should be effective anti-bullying programs implemented. These problems should focus on bystanders in particular because rather often they do not do anything to prevent or stop bullying when they witness it.

    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.
