Bullying in its truest form is comprised of a series of repeated intentionally cruel incidents, involving the same children, in the same bully and victim roles. This, however, does not mean that in order for bullying to occur there must be repeat offenses.
Bullying can consist of a single interaction.
Bullying behavior may also be defined as a criminal act if the bully is twelve years of age or older. However, every day in schools, many students witness bullying incidents as they happen, and this forces their involvement. Often, these students do not realize that what they are witnessing is, in fact, bullying. Good natured teasing and rough-housing are only fun if both parties involved agree that it is fun. The power difference between bullies and victims determines the nature of the interaction.
