You are halfway out of the chair and the mind insists you finish the sentence first. Mars squares Mercury, the body that wants to move dragging crosswise against the word that wants to put things in order. Bolt, and you have no explanation ready. Explain, and the moment to act slides past. It showed in arguments where your hands spoke before your tongue could, in long letters written instead of doing the thing you already knew how to do. What the grind welded together was coordination, tongue with feet. A whole decision carries both at once. Few people can explain a thing while already walking toward it. You can.
