Killer Defense

Waiting for them to knock on my door.
As broken glass lays on the floor.
It happened again.
When he came in around ten.
He was really drunk.
Even smelled like a skunk.
Why me I ask?
I always end up with an ass.
Blood on my body, gun in my hand.
This is not what I had planned.
I'm sure the girl down the hall
Had to hear it all.
She called the cops.
So I grabbed the mop.
It was self defense.
That's how it went.
Being raped and stabbed made me pull the trigger.
Blame me for killing the wigger?
