The blue moon slipped through empty spaces overhead and passed away from what it saw below.
A full moon slips in and out between the remnants.
The moon slipped behind the trees to join, briefly, her brother, sun.
So when the moon slipped behind the dark clouds the boys rose silently to their feet.
The moon, fat and red, slipped swiftly up the purple sky.
By the time she was ready to move on, the moon had slipped behind a cloud.
Like a bloated white snowball, the moon slipped by off to his left.
They woke when the stars had gone and the moon had slipped away.
The new moon had slipped behind the earth's sharp edge.
Now, watching the moon slip down toward the waves, they were completely alone.
