Just look at these two for a moment.

They are so very opposite from one another.  Very different.  And yet, they fit together so beautifully and perfectly.  The skin, the hair, the size, the shapes.  There is some serious yin-yang going on here.  Complementary forces, interacting to form a whole greater than either separate part.

If there’s a more beautifully matched couple out there, I sure haven’t seen it.
