A correct answer--WOOT!

Kate began the awkward transition of rotating slowly to the left while trying to keep her moon in place. It was awkward, because she found herself eyeing the moon, trying to keep it still, while also trying to move another part of her body. Kate had remembered studying the moon phases when she was being homeschooled by her mom. The moon always seemed like it was growing, even though it wasn't.

Then there were times when the moon seemed like it was shrinking, or waning she should say. "Is it the waxing gibbous?" she asked, her hand raised. It was the phase where the moon was almost full but not quite.
