You know you did it
I'm gone 
To find someone to live for in this world 
There's no light at the end of the tunnel tonight 
Just a bridge that I gotta burn 
You are wrong 
If you think you can walk right through my door 
That is just so you 
Coming back when I've finally moved on
I'm already gone
                                                -kelly clarkson-
