water flows up hill

Bingo. Water moving downhill (toward a more probably state) causes other water to move uphill (toward a more improbable state). Issue isn't quite whether we expect it or not (though that's a good touchstone), is the relative probability of starting/ending states. Things go "spontaneously" from more improbable to more probable (second law of thermodynamics). Things going in the other direction can (statistically) do so only when something else changes spontaneously.

Incorrect? Correct? .... Good story?
