a dance

A good relationship has a pattern like a dance and is built on some of the same rules.  The partners do not need to hold on tightly, because they move confidently in the same pattern, intricate but gay and swift and free ... To touch heavily would be to arrest the pattern and freeze the movement, to check the endlessly changing beauty of its unfolding... they know they are partners moving to the same rhythm, creating a pattern together, and being invisibly nourished by it.
