But isn't this a dance? Isn't all of this a dance? Isn't that what we do with words? Isn't that what we do when we talk, when we spar, when we make plans or leave them to chance? Some of it's choreographed. Some of the steps have been done for ages. And the rest--the rest is spontaneous. The rest has to be decided on the floor, in the moment, before the music ends.
