Texting is more direct. You don't have to use conversation filler.

Teenagers talk about the idea of having each other's 'full attention.' They grew up in a culture of distraction. They remember their parents were on cell phones when they were pushed on swings as toddlers.

What is so seductive about texting, about keeping that phone on, about that little red light on the BlackBerry, is you want to know who wants you.
