I am not what I am,
Nor am I what people say I am.

I am a locked box,
Full of things I cannot share.
I am sly as a fox,
Often portraying that I do not care.

But this of course is untrue.
What do I desire?
You and your unyielding fire.
And yet I can never seem to tell you.

Who am I?
I am the unknown.
