"Casual" lyrics

I woke up late and found on a page
Written in black and the words hit
You couldn't even stay to tell me in person
To tell me yourself it wasn't worth it

Right from the start I knew it was you
How did you hide it so simply
Right where you are it didn't take much
But you knew when you left I'd be empty

How do you keep yourself together
While you break me apart
But you're taking my place
And throwing me away

There you go like we're only animals
You're leading me on
You're going and you're gone
I don't think I could be so casual

Walking around, griping the paper
It's all that I've got of you here
Scratching the surface trying to remember
Trying to let go of so much

How do you keep yourself together
While you break me apart
But you're taking my place
And throwing me away

There you go like we're only animals
You're leading me on
You're going and you're gone
I don't think I could be so casual

And you think that you know someone
(That you know somebody so well)
Yeah you think that you know someone
But I guess I was wrong

You're taking my place
And throwing me away
There you go like we're only animals
You're leading me on
You're going and you're gone
I don't think I could be so

You're taking my place
And throwing me away
There you go like we're only animals
You're leading me on
You're going and you're gone
I don't think I could be so casual
