Bullying is an act of repeated aggressive behavior in order to intentionally hurt another person, physically or mentally. Bullying is characterized by an individual behaving in a certain way to gain power over another person.
Norwegian researcher Dan Olweus defines bullying as when a person is
"exposed, repeatedly and over time, to negative actions on the part of one or more other persons." He defines negative action as "when a person intentionally inflicts injury or discomfort upon another person, through physical contact, through words or in other ways".I think the word "intentional" is very important.
Self-defense, self-defence (see spelling differences) or private defense is a countermeasure that involves defending oneself, one's property or the well-being of another from harm.
- Author Katy Mattingly defines verbal self-defense as simply saying no to someone or repeatedly refusing a request or telling someone who has violated a boundary what you want, or it could entail a more complicated scenario in which you are called on to refuse to engage verbally with someone manipulative, to set limits, and end the conversation.
