I have always known my kids use digital communications equipment a lot. But my cellphone bill last month really grabbed my attention. My son had come up to nearly 2,000 incoming text messages, and had sent nearly as many. Of course, he was out of school for the summer and communicating more with friends from a distance. Nevertheless, he found time to keep a summer job and complete a college course in between all that typing with thumb. I was even more surprised to learn that my son is normal.

Beyond that,  though,  I'm not sure I see as much harm as critics of this trend.  I' ve posted before on how I initially tried to control my kids' texting. But over time, I have seen my son suffer no apparent ill effects, and he gains a big benefit, continuing contact with others. I don't think texting make kids stupid. It may make them annoying, when they try to text and talk to you at the same time. And it may make them _ when buzzing text message interrupt efforts to noodle out a math problem or finish reading for school. But I don't see texting harming teens' ability to communicate. My son is as accustomed to nonverbal cues as any older members of our family. I have found him more engaged and easier to communicate with from a great distance. because he is constantly available by means of text  message and responds with faithfulness and speed.
