I am

 A daisy in a pasture of roses, subtle and sweet

Like a cliff against a tsunami, unmovable and silent

The force of a stampede of buffalo, great and powerful

The roar of a fire on a cold winter night, familiar and safe

And yet,

I am

The roar of an engine in the middle of the night, startling and shocking

Like a massive avalanche rolling down a hill, crushing and without hesitation

The grinding of steel in a car crash, unrelenting and tragic

A thunderstorm in the middle of sunshine, unusual and breaking 

I am 

Everything and nothing, all at once 

I am Cheyanna.
