Through

While lying here in bed
 my thoughts have turned to you.
I'm thinking of how glad I am
for having all this room.
You once were such a part of me
and now we are all through.
If by chance you think of me
I'd have to say, "You're screwed!"
You've taken all you will from me
brought crazy to my room.
Why don't you just fly away
upon her whisk of broom.
You see I am different now
my heart not filled with gloom.
I have found a place without you
clear of all the doom.
I can finally say,"I was mistaken"
the faults are all on you.
So slink away quietly
for that is what you do.
I have gladly wiped you away
like a piece of shite on my shoe.
