Drawing a dead man

So short, but it reveals inner pain conflicted open others. This is why I write!!

He opens the door and asks why I'm selling my paintings.
He doesn't know yet but i'm going to kill him.
In the heat of the night, so still for once.
I said goodbye a long time ago, to everything, even my life...
even my art...
Artists feel pain, more intense, more gray scale.
I wanted to poison him, then draw him dead.
Why does he ask me things that kill me?
