I have notice that my adult grandchildren would have to have their cell phones surgically removed from their ears if they had to use only land lines. They HAVE to multi-task. Like talk to their friends on the phone every minute they are at home. The only time they don't talk is when they are texting. One will talk or text on the phone while she is on facebook on the computer. They aren't WITH people a lot, just TALK to people a lot. When I was their age I was WITH people. I think they miss out on a lot of socializing.
