They're feeling lonely and isolated. They're missing something important. We're losing human contact with one another, even though we don't mean to. We're otherwise engaged. We're somewhere else.
Strong connections make life feel satisfying and secure.
We might, for instance, spend less time watching TV or cruising the Internet and more time talking with our spouses. We could spend an hour each week reading aloud to our children. Outside the home, we might organize a neighborhood barbecue. We could learn our neighbors' names. We might attend a PTA meeting or a public issues forum or vote.
