Head couples cross over.
Balance and swing your partner
(with the look and the smile, and the centrifugal force of two bodies spending fact, ending in the perfect position for the next move).
Long lines forward and back
(most of the time crooked, but sometimes straight and in time to the wonder of all).
A quick breath at the end of the set,
as hearts beat fast, and a quick word is shared.
Then jump in again,
heading in the other direction,
until the caller ends it all
and the rush to find the next partner for the next dance begins.
