Bullying manifests as a repeated aggression, aimed at intimidating and hurting others on physical, psychological, emotional, or social levels. While it is highly common among children and adolescents, it may also affect different groups within society. Bullying often targets those who are isolated, introverted, or shy—individuals who may find it difficult to defend themselves. Those with learning difficulties, academic struggles, disabilities, or those who are new to the local culture can also become targets.
