Bullying is an attack upon the runts of the litter - the weak of the species, and it is predicated on a lack of bond with the parents. If a child has a secure bond with the parents, that forms a force-field around the child in terms of bullying. If the child does not have a strong bond with the parents, then it's like being separated from the herd - those are the ones who get picked off by the human predators in childhood and adulthood. So keep your contacts as close as you can, they provide an amazing shield against bullies and users.
