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. Now, their parents text at the dinner table and don't look up from their BlackBerry when they come for end-of-school day pickup.
