Now I do *snicker*.
"Now I do."
Most of the moons in the Solar System are tidally locked to their primaries. Tidal friction is unremitting, and has no corresponding impetus to balance it. Inevitably, the rotation comes to a stop.
But the moons go around their primaries at different distances, so even though they keep one face toward the main planet, they still have different lengths of "day".
The revolution, of course, has nothing but vacuum to slow it down, so the moons and planets continue going around pretty much endlessly. Vive la revolución!
