Stupid Blade Poem by something changing

Stupid blade
You think you know me
I hear you call my name
But in fact
You cannot know me
Or you'd let me suffer my pain

You wouldn't tempt me
You wouldn't call me
You'd leave me well alone
I'd never know you
Never use you
If you knew me you'd be unknown

So the fact stands
That you do not know me
You just tempt me with your lies
You tell me you know me
And that I can be happy
And I fall for it every stinkin time.
