I creep in with feline grace -
Stealthy, silent, gliding -
Adding beauty, mystery, and stillness to all in my path.
My shape is ever-changing:
Pausing and moving, here and there,
A cool caress across your cheek as I slip quietly by.
But my looks are deceiving -
Peril may lurk behind my misty veil.
Slow down, be cautious, or you may abruptly meet with danger there.
What am I?
