It's as easy as cracking knuckles...

It's as easy as cracking knuckles...
and as relieving as well. 
You were difficult at first; it hurt at first. 
It took a while before I got used to you, 
Got used to your whining, 
Got used to your rustiness, 
Got used to you. 

And then I didn't.
I didn't want to.
I didn't want to get used to you.
But when I tried to foget you...
When I tried to fold you up and stick you in the back corner of my brain...
you came back...all stiff and achy. 

And I had to bend my finger backwards;
you became my remedy again. 
Slowly my knuckles swell...
