You're allosteric babe
You changed the way I keep
With no defense
It must've been so easy

Nothing but respect
For the words you said to me
There's not enough of everything 
To keep anything forever

I don't function like I used to
And maybe thats alright
I was spinning out of control
My heart just felt so light

Heaviness returned
So rapidly when you spoke
Of what I don't deserve 
It left me an understanding 
Of exactly who you think you are

Now I'm grounded to the spot
My heart is heavy in its box
But no more energy is lost
For something that wont last

Allosteric and present
Maybe I'll function properly 
When the memory
Dissipates
