So, now you're leaving?

So now you're leaving are you?
After all my fervent prayers,
There is no demon left for me to loathe;

You've emptied out the wood bin;
You leave an empty husk;
Your flight is vanguard of my many oaths;

Eight long years you've fed my hate,
Drawn out eight years of venom;
Now bumble in your idiotic sty;

Too dim to know the nature,
Of the damage you have wrought;
Please don't insult us both by asking "Why?"
