Thanks for nothing

Opportunity don't you hear me knocking?
Why won't you let me in?
Behind closed doors are you mocking?

I'm asking for a chance begging you for mercy
At a loss for words for shunning me I curse thee

Pounding on what seems like steel
I hunger for sustenance
Can you spare me a meal?

I come with humility
Your lacking compassion
These consequences for my actions
So hard to imagine
