I know beauty

I am angry I am ill and I'm as ugly as sin
My irritability keeps me alive and kicking
I know the meaning of life, it doesn't help me a bit
I know beauty and I know a good thing when I see it

This is a song from under the floorboards
This is a song from where the wall is cracked
My force of habit, I am an insect
I have to confess I'm proud as hell of that fact
