That behavior is appalling. Those who would picnic in a graveyard disrespect not only the lives that were lost on that sacred ground, but also those soldiers still in harm's way as a result of the events that gave rise to that memorial. But such behavior is in keeping with a pattern.
Despite the best of intentions, too often we do forget too soon.
April 19 marked the 17th anniversary of the Oklahoma City bombing, the day on which 168 innocents lost their lives, including 19 young children.
One day later, April 20, was the 13th anniversary of the Columbine school shootings, in which 12 students and one teacher were murdered by two students who then killed themselves.
Closer to home, May 13 marked the 27th anniversary of the MOVE conflagration that claimed the lives of 11 people, five of them children.
Ever heard of Harold Unruh? Wednesday was the 63d anniversary of the day Unruh murdered 13 of his neighbors in Camden.
And come Nov. 22, the nation will mark the 49th anniversary of the assassination of President John F. Kennedy.
Each of these was a monumental day based on tragedy, but for how many of them do we now pause? All were events that were "the" news for a period of months, and, in every instance, there was grieving accompanied by the refrain of "never forget." But life does go on. And when witnesses and loved ones of the victims die and memories fade, the challenge of remembering grows more difficult.
Ensuring that Sept. 11 stands apart will require community and individual action.
This weekend, churches should be noting the coming anniversary.
On Tuesday, 9/11 should be part of every school's lesson plan.
Employers should find a way of noting the occasion, in keeping with the decorum of the workplace.
Flags should, of course, be flown at half-staff.
And the media must keep showing the harrowing footage of the airplanes hitting the Twin Towers. More than anything else, if that presentation were shown with more regularity - beyond just the anniversary newsreels - it would go a long way toward keeping us ever mindful of what transpired 11 years ago.
Most important, at dinner tables across America, Tuesday night needs to be a time for parents to share with their children the perspective of where they were 11 years ago, what happened to the nation, and with what consequence.
We won't forget. But unless we take these measures and more, those who follow us will.
