Of course, there is no one cause of bullying, but several factors have been cited with helping foster it. The major indication of bullying is life at home. Children that are neglected, abused or even bullied they at home will likely do the same to their peers. It was previously believed that bullies had low self-esteem and unpopular, but research is finally seeing that a lot of them are actually quite popular and confident. Those who do not receive attention, discipline and affection from parents are also to be bullies. While bullies of course come in all shapes and sizes, they do share some similar characteristics. They tend to be aggressive and dominating; although again just because someone acts that way does not mean that they will become a bully.
