A Gentle First Twitch

Oh dear... is it safe to move? Everything around me was so completely still, until a tiny warmth gathered in my toes. I took a very slow, cautious breath and tested my right foot. It actually shifted—just a millimeter—on the smooth shelf. Down between my shoes, a small yellow butterfly figure sat frozen in the chill. I reached out one trembling blue finger and gently tapped its wing, half expecting an alarm. But there was only quiet. It appears... I can really move?
