Some teen ager been careless with life specially in this era, not all feel loved. They'll find love in a wrong way by being with so called friends but that circle of their are not always good one, some are being a bad influence, why some teenager end up in a poor situation? First maybe how they are raise cause not all teenagers are having a peaceful family, some family are being busy and can't took care their childrens properly cause maybe they are busy with their work or some stuff but then we can't blame them cause it is for their children but not all children can't understand it. Some teenagers raise well, why? Cause they can understand and they are well manered. ~Zhie
