The wind

It's like the wind,
You can't see it coming,
But you could just feel it.
It's like air you breathe,
You don't realize it's there,
But you just actually need it.
It's like the silhouette of the wind,
It will just be there,
Before you even know it.
You could feel it,
You could not steer clear of it,
It will just,
Always be there.
