suddenly

My commute yesterday morning began so uneventfully;
Traffic steaming together toward some invisible destination.
There was road construction as always.
There were lane changes and traffic lights as usual.
The weather was blandly clear, and even the skies held no hint of the unexpected.
And that was probably why I gasped so loudly when the unexpected appeared.
Suddenly,
right in front of me,
flying low,
were five swans.
Five huge, snowy white swans, their necks stretched out, their winds spread wide,
streaming towards some invisible destination.
