Having just waited all weekend for a cell phone to arrive by “express” mail to replace a dead one, I know how Arlo feels. For three days, I reveled in the awareness no one could telephone me. To visit the grocery store or the feed-and-seed was to enjoy a small freedom we’ve largely forfeited, the freedom to be incommunicado. However, I was a bit let down when my new phone finally arrived, and I discovered only three people had attempted to call me in three days, and one of those was trying to return my call to him.
