There are lots of reasons why a woman stays with a man, even when she's given up on changing him and can predict with certainty the shape that the rest of her life with him is going to take.
The form is mechanic when on any given material we impress a predetermined form. The organic form, on the other hand, is innate, it shapes as it develops itself from within.
The whole point with type is for you not to be aware it is there. If you remember the shape of a spoon with which you just ate some soup, then the spoon had a poor shape.
