You get your children cell phones so you can keep in touch with them.
They in turn use them to keep in touch, at all times, with whom do I know.
They keep their cell phones on their bodies practically at all times, since they contain so much personal information. If I could get my hands on them, I would drive over them (the cell phones).
You see your kids for a few moments in the day when they are almost grown up, and they only care about their text-messages! You speak to them a few sentences and they have another text message. Even in the dental chair, all the young folks are texting. They can do it blind-folded, lying down with their mouth open.
