Most of us have experienced impromptu community, an unexpected incident that binds us to the people around us. Passengers on a plane bound for the United States on September 11, 2001, had to land unexpectedly in Newfoundland, Canada, when U.S. airspace closed following terrorist attacks in the U.S.

The Newfoundlanders showered unexpected hospitality on the passengers, lodging them in schools and churches, and feeding them. This hospitality, coupled with the horrifying events of the day, bonded the passengers to each other as well as to their hosts.

Perhaps a serendipity, a surprising moment of grace lifts us up. Eventually, the moment passes and we return to our own lives. Yet, that transforming moment pushes us gently toward hope.

A friend sent me a link to such a serendipity. First: a pedestrian square filled with tourists, couples, babies in strollers, children, the bored, the young, and the old. Then it becomes, for an instant, a community through the power of music.

Listen to the music, but watch also the touch of a sudden community.
