And I think it is because dancing is the truest small picture of a marriage there is.

To dance with someone is to agree to move together — to lead and to follow, to feel the next step in the other’s body before it comes, to trust that when you turn away they will be there when you turn back.

It requires attention, constant and mutual; the instant you stop paying attention to your partner, you step on each other.

It cannot be done while distracted.
