ALAS PLEASURE IS NO MATCH

You are describing the mutual feeling of helplessness in face of pain
like when you can see a child is about to fall

I am thinking Thanks For Explaining Porn

convoluted way that I have of arriving there from your empathy

Also, there are bluish shadows

where your words are hitting the wall 

of the strange and white room of this conversation

Alas, pleasure is no match for pricks of conscience
inarguable flick of trouble amidst constant weighing.

As for fingernails, I prefer the moon.
