One day in 2012, a group of policemen in a Danish town were sitting around in the office when an unusual call came in. This town, called Aarhus, is a clean, orderly place with very little crime. So what the callers were saying really held the cops' attention. They were parents, and they were "just hysterical," recalled Thorleif Link, one of the officers. Their son was missing. They woke up one day and he was gone.

A few weeks ago at a soccer game I was coaching, my team got trounced. They are 7 and they are not used to losing. As soon as I called the game and they realized what had just happened, two of the boys burst out crying.
