Dead girl

I used to be someone's good girl
When he punched a hole in the wall
I covered it up with a red, black and green flag
Because I pretty up a room like nobody's business
Because it was nobody's business
When I told him I had a headache
He said "That's ok. I don't want to fuck your head anyway."
I smiled like I got the joke
Like I was the joke
I was a good girl and then he killed her
And I became the woman before you now
I wonder if I should track him down and thank him
