Childhood bullying is often noticed when physical signs, like bruises and cuts, are present. Although we generally can see the signs of physical bullying, there are other harmful forms of bullying that occur in childhood circles. An even more painful type of bullying is one that hurts a child on the inside. This relational bullying is a hidden type of aggression ( or hostile behavior) where peers harm "others through purposeful manipulation and damaging of their peer relationship"1 (1995).
