"that was my brain on elves" lyrics

I happened to be awake
When the postman came with your latest package
He made a remark about the frequency of orders
Something about destroying the rainforests
And it made me think about death
But not in a way that would make you unhappy
I realized the things that we buy are an island
And it's there that I want to be buried

But that was my brain on elves
That was my brain on simple pleasures
That was my only vice
That was my only vice

I was quietly congratulating a bitter former lover
On a brand-new job with BAE Systems
But she grabbed me by the throat and arrested my breathing
In the way she might have subdued a chicken
And it made me think about meat
But not in a way that prepared me for dinner
I understood, finally, that animals have feelings
But not in a way they can monetize

But that was my brain on elves
That was my brain on object permanence
That was my only vice
That was my only vice
