We belong to an institution where kids would do this sort of thing regularly. The director's response was, "What can we do?" We actually found that we could report the situation to MySpace and they would take action.
So many people don't understand that it is the adults' job to run the world and the kids' job to be run.
Shalom.
Amen. Too many parents allow their children to run the family, to the detriment of the children. Let the parents be the adult and the kids be the children.
