Creaking Crystals

I let my ears listen 
As I stick my head out the window.
The air is still,
only the cold touches my cheeks.
Traffic sounds are absent,
The snow reflects starlight back to me. 
My ears keep tuning near and far.
They find a creak, and another, 
The sound of an unfreezing crystal
As it pulls on the neighboring crystals.
I smile, feeling special.
I doubted that anyone else heard those particular crystals.
