Your kids, like mine, probably communicate with their friends mostly through the written word - email, text, etc. Interesting, though, that The New York Times recently ran a piece about hugging in school.
One of the conclusions was that perhaps kids hug more now because most of their communication, otherwise, is through a computer screen of some sort.
Interesting. What does this mean for us as communicators? Maybe it means that as companies continue to communicate through a variety of media and even though they are "always on," those with whom we are communicating still crave real interaction.
