Unfortunately, this is a part of life. Young girls will always meet creeps who will push the boundaries. Each girl must learn how to deal with them in their own individual way. It stinks but that’s life.
One method is getting adults you trust to stand up for you, believe you and deal with the creeps.
Some women have such a shy and timid personality that they are lambs to be slaughtered. You can’t just tell them, toughen up and learn to deal, because they can’t anymore than a real lamb can stand up to a real wolf.
