The ebb and flow, but beyond that. It's more than the waves, more than the moon could ever define. It's something even nature can rarely define; the grass doesn't flux in the breeze, the blossoms don't flux during spring, and the sun certainly doesn't flux in all its brilliant glory. Maybe a firefly's light could flux, in and out of your vision. But flux usually has to do with energy- as you run, your energy fluxes up and down your pumping muscles. The flux of life. Of light. Of everything.
Obedient is the dog that stays when told. Obedient, possibly, is the sun and moon as they rise and set at their respective times. And, if the meaning is to be stretched, obedient is the wind as it tips the hunter's bullet in his favor. But never, ever, is it to be applied to people. To women or men, or even child. The girl is not obedient. The wife is not obedient. Never. It boils me up with rage.
